An obese cat is not a pretty sight. Cumbersome and clumsy, they suffer a marked loss in athletic ability and appearance. Decreased flexibility prevents them from thoroughly grooming, which can cause skin problems. Obese cats also have an increased risk for diabetes and are poor candidates for surgery and anesthesia.
Obesity results when an animal consistently eats more calories than they need. This can be caused by overfeeding, inactivity, reproductive status, environment, body type, age or genetics.
Assessing body condition is important in the overall evaluation of your cat’s nutritional well-being and can help in determining feline obesity. Take a few moments to follow the easy directions in the Cat Body Condition Chart for assessing your cat’s body condition.
If you suspect your cat is obese, the first step is to consult your veterinarian.
Your veterinarian will probably ask you some questions about your cat, such as how much they eat and how much physical activity they get. Answering these questions honestly will help your veterinarian recommend some simple changes to help improve your cat’s weight. Your veterinarian may also perform tests to detect medical conditions that may contribute to obesity — you want to rule these out before starting your cat on any weight-management program.
Your veterinarian may first suggest reducing the amount you feed your cat. If so, begin by reducing the daily portion by 25%. Continue decreasing intake by 10% increments every two to three weeks until your cat loses 1% of their starting weight. For example, if your cat weighs 15 pounds, a 1% loss would be 2½ ounces.
If you feed one large meal a day, or keep food available at all times, try dividing the daily ration into several small meals (at least two meals a day) and pick up what your cat doesn’t eat 30 minutes after each meal.
A diet that contains slowly digested carbohydrates, such as corn and sorghum, can result in lower blood sugar and insulin levels than a diet that contains rice as the primary carbohydrate source. Lower blood sugar and insulin levels can also help with maintaining a proper weight.
Changing diets can be stressful for pets, so if your veterinarian recommends changing diets, proceed slowly.
Begin with a daily portion that mixes 25% of the new food with 75% of the old food. The next day, increase the amount of new food to 50% and decrease the amount of the old food to 50%. During the next few days, continue increasing the proportions of the new food and decreasing the amount of old food until the food consists entirely of the new diet. This method increases the likelihood that your cat will accept the new diet and decreases the occurrence of stomach upsets.
Another way to help your cat lose weight is to increase their activity. Provide cat trees for climbing, or teach your cat to play fetch or walk on a leash. Buy or create your own toys that encourage exercise. One ingenious owner tosses her cat’s dry food ration across the room a piece at a time!
You also can use your cat’s natural hunting instinct to help them lose weight. Hide several small portions of their daily food ration around the house. If you have a multilevel home, make your cat use the stairs.
Use your imagination, but be cautious. Don’t let a fat cat get exhausted, overheated or out of breath. Also, keep in mind that a senior cat may not be able to exercise vigorously.
Replace food treats with rewards like playtime, grooming, stroking or conversation. If you cannot resist the fat cat who begs for food at the dinner table, keep them in another room during dinnertime. If you have a multi-cat household, the consistent winner of the food competition sweepstakes is often obese. If this is the case, separate the cats at mealtimes if possible.
Obesity is easier to prevent than to cure, but it is never too late to reverse it — though it requires long-term patience and commitment. Helping cats lose weight is a slow process. If the amount they eat is severely restricted, the cat risks other health problems.
Increased activity, behavior modification (for both you and your cat) and calorie restriction are your best tools for helping an obese cat lose weight. However, it is important to expect a few setbacks and plateaus. It will take at least four months for an obese cat to lose 15% of their starting weight. At that point, have another look at your cat’s body condition and go from there.
Tips for Starting a Weight-management Program for Your Cat
Nutrients such as protein, fat, vitamins, and minerals are important players in the skin and coat health of dogs and cats. To understand their role, it is necessary to first understand skin and hair.
The purpose of skin and hair is to block things (such as water or heat) from leaving, or things (such as viruses and bacteria) from entering the body.
The hair coat is composed almost entirely of protein. If an animal's diet doesn't contain adequate protein quantity and quality, hair may fall out, or become dry, weak, and brittle.
Skin is made up of squamous cells, which are flat cells tightly packed together. These cells have tough membranes that are composed of proteins and fats. Without proper amounts of these nutrients, cell membranes weaken, allowing water to escape and bacteria and viruses to enter more easily.
Proteins are found in both animal-based and plant-based ingredients. Animal-based proteins contain all the essential amino acids cats need, whereas plant-based proteins may contain only some essential amino acids. Cats need animal-based proteins to achieve optimal health.
Fats also can be found in both animal-based and plant-based ingredients, and they are incorporated into skin cells as fatty acids. There are two essential fatty acids for skin and coat health. Linoleic acid maintains skin and coat condition in dogs and cats. Without enough linoleic acid cats may experience dull, dry coat, hair loss, greasy skin and increased susceptibility to skin inflammation. Cats also require arachidonic acid for normal skin and coat health.
Both of these essential fatty acids are omega-6 fatty acids and are found in animal tissues such as chicken fat. Linoleic acid is also found in some vegetable oils, such as corn and soybean oils. Most commercial cat diets contain more than adequate amounts of omega-6 fatty acids.
Because these fatty acids can be converted to compounds that increase susceptibility to skin inflammation, it is important to balance the amount of omega-6 fatty acids in the diet with omega-3 fatty acids, which do not reduce susceptibility to inflammation.
Omega-3 fatty acids are found in oils from fish and some plants (canola and flax).
IAMS™ research has found that combining fat sources in the diet at a ratio of five to 10 omega-6 fatty acids to one omega-3 fatty acid results in excellent skin and coat health.
Vitamins and minerals are essential for the development of healthy skin and hair coat. The best way to provide these nutrients is through a complete and balanced diet containing appropriate amounts of essential vitamins and minerals rather than through supplements.
Vitamin or Mineral | Important for Skin and Coat Health |
Vitamin A | Necessary for growth and repair of skin |
Vitamin E | Protects skin cells from oxidant damage |
Biotin | Aids in the utilization of protein |
Riboflavin (B2) | Necessary for fat and protein metabolism |
Zinc | Necessary for fat and protein metabolism |
Copper | Involved in tissue, pigment, and protein synthesis |
Diet is often believed to be a factor when changes in skin and coat condition are noticed. The most common causes of these changes, however, are season and life stage.
As cold weather approaches, most dogs and cats grow a thick coat to help keep heat in and cold air out. As the weather begins to warm up, they shed the thick, heavy coat.
Most kittens are born with soft, fuzzy hair, but as they age, a coarser coat grows. Pregnant or lactating cats also may experience a change in coat condition or hair loss.
