Beat the Heat: Summer Care Tips for Cats

The summer is a great time to get outside and enjoy the warm weather, but you may want to leave Kitty indoors while you frolic in the sun. While it's easy for you to keep cool when temperatures rise, cats have a much more difficult time when it comes to beating the heat. Here are some tips to keep your feline family members nice and cool in the summer.

Cats generally handle warmer temperatures better than dogs, but owners should remain vigilant about Kitty during the summer months. The easiest way to keep your cat cool in the summer is to keep him or her indoors during the hottest parts of the day. If you do let your cat venture outside, do so early in the morning or at dusk when the temperature is cooler and there is more shade from the sun. While your cat is inside, keep plenty of fresh, cool water available throughout the house. If the weather is extremely hot, consider wrapping your cat in a cool, damp towel or placing a plastic bag full of ice under their bed.

Keep your cat cool during the summer months

When the weather is extremely hot and humid, cats can be prone to heat stroke. Very old cats, as well as obese cats and those with existing health problems are especially susceptible to heath stroke. Owners should also be aware of signs of heat exhaustion and heat stroke. A cat's normal body temperature should be between 100.5 degrees F and 101.5 degrees F. Any temperature higher than 102 degrees F is dangerous, and immediate action should be taken to lower the cat's temperature. If a cat's temperature increases to 107 degrees F, he or she is possibly suffering the effects of heat stroke.

Signs of heat stroke include:

  • Panting
  • Staring
  • Anxious expression
  • Warm, dry skin
  • High fever
  • Rapid heartbeat
  • Vomiting
  • Collapse

If your cat begins exhibiting any of these symptoms, call your veterinarian immediately. To cool your cat down, remove him or her from the area and apply towels soaked in cool water to your cat's skin. Immersion in a cool water bath for 30 minutes may also help lower your cat's temperature. While on the way to the veterinarian's office, place ice packs around your cat's head and body. No matter how you cool your cat off, you must bring him or her to a veterinarian as intravenous fluids may be required. Heat stroke can be fatal if left untreated.

Keep your cat cool during the summer months

Even though Kitty is covered in a fine coat of fur, she is just as susceptible to sunburn as you. Cats with white coats or white ears and faces are particularly prone to feeling the effects of the sun's rays. And while sunburn is discomforting for your cat in the short term, it can also have long term effects. Extended exposure to direct sunlight can lead to squamous cell carcinoma, a form of cancer that usually appears at the tips of the ears and on the nose. Signs of squamous cell carcinoma include sores that bleed excessively or do not heal. The best way to protect your cat is to keep him or her out of direct sunlight in the summer time. If your cat is going outdoors, you can protect his or her skin with an application of sunscreen; however, be sure only to use a sunscreen formulated for cats. Sunscreen not designed for cats can result in drooling, lethargy, diarrhea and excessive thirst. Ask your veterinarian about sunscreens that are right for your cat.

Your cat may also face other, non-weather-related problems in the summertime. Cats outdoors for a roam may be tempted to take a taste of antifreeze puddles they find in streets and driveways. Antifreeze is extremely toxic to pets—it only takes one to two teaspoons of antifreeze to poison a cat. Symptoms include vomiting, excessive thirst/urination, depression and a wobbly gait. If you suspect your cat has ingested antifreeze, get him or her to a veterinarian immediately. Owners should also make sure there are no open, unscreened windows in their homes. Adventurous cats may jump or accidentally fall out of open windows, leading to broken bones and other injuries.

Summer can be a carefree, easy time for you and your pet, so long as you both play it safe and keep cool. Ask your veterinarian if you have any questions about beating the heat this summer.

Fireworks Are Dangerous to Your Pet

If you thought it would be harmless to mix pets and fireworks, think again. All fireworks should be kept at a safe distance from curious and unsuspecting pets. Anything from small smoke bombs and sparklers to large aerial displays has the potential to cause severe burns. The face, mouth and paws are the most common places pets get burned by fireworks. Furthermore, fireworks can also contain heavy metals that are used as coloring agents and may cause poisoning if ingested. Symptoms of heavy metal/fireworks poisoning include vomiting, lethargy, diarrhea, jaundice, tremors and seizures.


If your pet may have ingested fireworks, immediate examination by a veterinarian is recommended. Do not induce vomiting at home as it can cause severe burns, especially in the mouth and upper gastrointestinal tract. While the prognosis is good in many cases involving the ingestion of small fireworks and minor burns, that is often not the case when the pet has ingested several fireworks. This is due to liver and nerve damage.

As you enjoy your holiday, remember to use common sense, and always put safety first for all family members.

How to Keep Your Dog Cool This Summer

People usually prepare themselves for the dangers of increased temperatures. But as the dog days of summer approach, our trusted companions also need special attention to insure that they don’t get burned. Like for us, the summer months bring an increased danger of heat exhaustion and heat stroke for dogs.

People naturally regulate their body temperature by sweating. Dogs mainly cool themselves by panting or breathing in through the nose and out through the mouth. The process of panting directs air over the mucous membranes (moist surface) of the tongue, throat and trachea (windpipe). The air that is flowing over these organs causes evaporation, thus cooling the animal. Another mechanisms that helps remove heat includes dilation of blood vessels in the skin of the face, ears and feet. Dilated blood vessels located on the surface of the body cause the blood to loose heat to the outside air.

A dog’s normal body temperature is 100.5 to 102.5 degrees Fahrenheit. Like people, dogs can become overheated. If it rises to 105 or 106 degrees, the dog is at risk for developing heat exhaustion. If the body temperature rises to 107 degrees, the dog has entered the danger zone of heat stroke. With heat stroke, damage to the body can be irreversible. Organs begin to shut down, and veterinary care is immediately needed.



Fortunately, if owners recognize heat exhaustion, they can prevent the dog from entering heat stroke. People can easily recognize when the heat gets to them because they become lightheaded and fail to sweat. For dogs, early signs of heat exhaustion may include failure to salivate and a dry mouth. Heat exhaustion may also include a dog lying down and looking tired, losing its appetite and becoming unresponsive to owners.

If heat exhaustion progresses into heat stroke, the dog becomes very warm to touch and may have seizures. Internal mechanisms roll into effect that may cause blood clotting and organ damage. If you are near a phone and think that heat stroke is a possibility, call your veterinarian immediately. If a veterinarian is not within reach, or while waiting for a veterinarian, get the dog out of the sun and cool him or her down with cool water baths (cool—not cold). Provide a fan, especially if you wet the dog down, and encourage him or her to drink water.

While these steps may help a dog, the best treatment is prevention. In order to prevent overheating, some owners may shave their dogs or trim their fur excessively. This isn’t always a good idea. The hair coat may appear to be a burden for a dog; however, it can also keep the animal comfortable by trapping cool air next to the skin, reducing the amount of heat transferred from the hot outside air to the body of the dog.

Dogs with long or thick coats that have problems with matted hair are often good candidates for clipping. Matted hair can cause skin irritation and is undesirable. Owners that do not have time to adequately remove mats and debris from their dog’s coat may prefer to have the coat clipped short. After a short clipping, and if the dog is outdoors, owners need to be careful of sunburn. Sunscreen may be applied to the dog’s skin; however, it is necessary to consult a veterinarian to find out which ones are safe.

Here are some other tips for keeping your dog cool this summer:

  • Keep dogs indoors in air conditioning on very hot days.
  • Do not leave dogs in a car during the summer. Even with the windows down, temperatures inside a car can quickly rise to above 120 degrees. Make sure outdoor dogs have plenty of shade.
  • Keep fresh water available at all times.
  • On very hot days, exercise dogs early in the morning or late in the evening. If this is not possible, exercise in an air conditioned environment.
  • Provide your dog with a sprinkler or wading pool on very warm days.
  • If you take the dog to a lake, make sure it has plenty of time to drink and get wet. Most dogs can drink lake water without adverse effects.
  • If your dog has a light coat or exposed skin, take precautions against sunburn.
  • Dogs can acclimate to warm temperatures and have no trouble staying outdoors in the heat. However, dogs that are used to cool climates or air conditioning should not be left outside on hot days.
  • Acclimating your dog gradually is the key.

If you have questions about caring for your dog during the summer months, please give your veterinarian a call.

Celebrate Thanksgiving Safely with Your Pets

Thanksgiving is a wonderful time to gather with family and friends and indulge in delicious holiday treats. You can be sure that if your cat or dog is around for the festivities, they'll want to share some of the goodies, too. But no matter how much your pets purr, plead, whine or whimper, owners should remember that holiday treats that are tasty for people can be potentially harmful for pets.

Thanksgiving foods may look tasty to your pet, but they could be harmful.

The typical Thanksgiving spread is flush with a variety of foods, from savory fare like turkey and stuffing to sweet foods like yams and cream pies. Your pet's diet is much blander and boring, and for good reason—foods with lots of fat, dairy and spices can cause vomiting and diarrhea in pets. For this reason, it's best to avoid letting Rover dine on the usual turkey day leftovers. If you must give your pet some holiday foods, stick to dishes like boiled potatoes or rice, which will not upset your pet's stomach.

Some holiday foods, however, can cause much more than an upset stomach in your pet. Garlic and onions are members of the allium family and, if eaten in large quantities, can cause hemolytic anemia, a blood disorder that causes red blood cells to burst. Raisins and grapes are also toxic to pets and have been linked to kidney failure.

Chocolate is one of the most dangerous foods that pets can eat—it's also one of the most prevalent holiday foods. Whether chocolate is found in cookies, cakes, truffles or baking squares, any amount can be dangerous. Chocolate contains theobromine and caffeine, both methylxanthines that can cause stimulation of the nervous system, increased heart rate and tremors. Signs of chocolate poisoning include vomiting, diarrhea, seizures, hyperactivity and increased thirst, urination and heart rate.

Chocolate is dangerous for pets

Other sweet treats, like gum and hard candies, can also make your pet ill. Sugar-free candies and gum are made with xylitol, a sugar substitute that can cause a drop in blood sugar, depression, loss of coordination and seizures in your pet. Xylitol is also linked to liver failure in dogs. Be sure to keep all candies, chocolate and other sweets out of your pet's reach. If you believe your pet may have ingested chocolate or candy, call your veterinarian immediately.

You may also be tempted to give your dog a leftover turkey bone or two once the table is cleared. However, poultry bones are small and easily breakable and can easily shatter and get caught in your pet's throat. These bones can cause damage to your pet's throat or lead to choking.

Holidays can also be as stressful for your pet as they are for you. Large gatherings of unfamiliar people may cause your dog or cat unnecessary stress and worry. If your pet does not interact well with strangers, keeping him or her in a separate room during the festivities may help keep your pet relaxed and worry-free.

During holiday gatherings, it's a good idea to keep your veterinarian's phone number handy. If your pet does get a hold of some Thanksgiving food and experiences mild vomiting or diarrhea, you can help settle their stomach by withholding food for a few hours then feeding small amounts of boiled rice and cooked hamburger. If the symptoms persist, contact your veterinarian immediately.

November is National Pet Diabetes Month

November is National Pet Diabetes Month, but with more than 50 percent of the nation’s cats and dogs overweight or obese, raising awareness of the common endocrine disease has been extended to pets – rather than just their human caretakers. It is estimated that one in every 200 cats may be affected by diabetes, being the most common endocrine condition found in felines. The numbers for dogs are similar and only expected to increase.

Diabetes results when a pet’s body doesn’t produce enough insulin (Type I DM) or doesn’t process it properly (Type II DM). When your pet eats, carbohydrates found in his or her food are converted into simple sugars, one of which is glucose. Glucose is then absorbed into the bloodstream through the intestines and travels to cells throughout the body. Inside cells, insulin typically helps turn the glucose into fuel. However, when there isn’t enough insulin, glucose can’t even enter the cells to be converted into energy and instead just builds up in the bloodstream.

Symptoms of Diabetes in Cats and Dogs:

• Lethargy
• Excessive thirst
• Frequent urination
• Always hungry, yet maintains or loses weight
• Thinning, dry and dull coats in cats
• Cloudy eyes in dogs


At-risk pets include:

• Those with genetic predispositions
• Those with other insulin-related disorders
• Those who are obese and/or physically inactive
• Dogs who are between 4- to 14-years-old
• Unspayed/intact female dogs are twice as likely to suffer from diabetes
• Dog breeds with greater risk for development: Cocker spaniels, dachshunds, Doberman Pinschers, German shepherds, golden retrievers, Labradors, Pomeranians, terriers and Toy Poodles

Although diabetes can’t be cured, it can be managed so that symptoms are reduced or eliminated entirely. Your veterinarian will decide which treatment options are best for your pet. Often, changes in diet and lifestyle, combined with or without daily insulin injections, can help your pet live a happy, healthy, active life.

If you’ve noticed any of the above symptoms in your pet and suspect he or she may have diabetes, contact your veterinarian today. Veterinarians are the only professionals who can accurately diagnose your pet and provide proper health management. Diabetes can affect a pet differently over time, even if your pet has experienced a long period of stability. The sooner your pet is diagnosed, the better, and the less likely you'll incur the cost of an expensive emergency visit for diabetic complications.

Advantages Of Spays and Neuters

Spaying or neutering pets is a common procedure, and most pet owners have probably had some experience with having the procedure done on animals they have owned.

Aside from the inconvenience of heat cycles and/or roaming tom cats, there are medical benefits associated to having your pet spayed or neutered. The direct health benefits of spaying or neutering are significant for the pet. If female pets are spayed before their first heat cycle, the risk of developing mammary tumors (breast cancer) is significantly reduced. Spaying female pets eliminates the risk of pyometra, an infection of the uterus. This disease can be very serious, even fatal, in female pets. Male pets can also benefit. Neutering eliminates the risk of testicular cancer and reduces the risk of prostate disease.

Spaying or neutering can indirectly help prolong a pet's life as well. When pets are spayed or neutered, their tendencies to roam or fight are greatly reduced. This prevents the pets from getting lost, stolen, hit by cars, or contracting a contagious disease.



Cats that fight are at risk of contracting a serious disease called feline leukemia. This disease, which affects the immune system of the cat, can be passed from feline to feline through saliva or blood. Cats also run the risk of contracting feline immune deficiency virus when they fight. This disease is very similar to human HIV. It can lie dormant in the cat for quite a while, and when activated, can cause the cat's immune system to function improperly.

Spaying or neutering dogs can help keep them under control. Dogs that have not been spayed or neutered are more likely to wander away from home. While running loose, they have a chance of being hit by a car, getting lost, stolen or taken to the animal shelter.

Even though spays and neuters are considered routine surgery, there is nothing routine about any abdominal surgery performed under general anesthesia. Most veterinarians consider spays and neuters to be major surgery, especially when spaying older animals that have had several heat cycles or have had litters.

Veterinarians and humane societies advise pet owners to have their pets spayed or neutered. The medical advantages have been proven. Complications resulting from these procedures are rare and pets recover from surgery very quickly. Often the day after surgery, animals are bright and alert, sometimes seeming as if nothing had ever happened.

The cost of the procedure varies depending upon the species, sex, size and age of the pet.

Emergency Kit For Your Pet

Of course, the best way to handle emergency situations is to avoid them by keeping your pet safe and healthy. However, in spite of your best efforts, accidents can happen. Here are some tips to consider before you need to use them.

Pet First Aid Kit

Always keep within reach the phone numbers for your veterinarian, emergency clinic, poison control center, etc. Keep a copy of your pet's health records where you can easily find them. You may also want to invest in a book that covers first aid procedures. Ask your veterinarian for recommendations. For example, the ASPCA's Complete Dog Care Manual and Complete Cat Care Manual have excellent information on first aid principles, as well as what to do in case of traffic injury. The book also contains useful information on how to perform artificial respiration and what steps to follow in case of poisoning, burns, insect bites, etc.

Have a pet carrier so you can safely transport your pet to an emergency clinic or veterinary hospital. Remember: An injured or ill pet may not act like its normal, sweet-tempered self. Handle the pet with care so you don't get bitten or scratched and need emergency treatment yourself!

Keep an emergency kit on hand with such items as:

• Bandages

• Adhesive tape

• Cotton

• Antiseptic cream

• Sterile dressings

• Gauze

• Thermometer

• Tweezers

• Scissors

• Blanket
