Cats + Diet & Nutrition

  • Critical care patients in the hospital are at risk of becoming malnourished, and poor food intake can delay healing and recovery. When hospitalized patients don’t get adequate calories and nutrients, their cellular metabolic activities are disrupted. They can develop problems with medications - either with inadequate drug activity, or creating a relative overdose if drug elimination is slowed. Critically ill cats that are not eating well on their own can directly benefit from the nutrition support provided by a feeding tube.

  • Cat food labels can certainly be confusing to interpret. In the United States, the Association of American Feed Control Officials (AAFCO) has developed model laws and regulations that states use for animal feeds. In Canada, pet food labeling guidelines are regulated by the Consumer Packaging and Labeling Act administered by Industry Canada. The Canadian government's Competition Bureau also has an extensive working group that upholds a voluntary code of conduct for the labeling and advertising of pet food. The most important information when comparing one dog food to another is the guaranteed analysis. Ingredient lists are somewhat useful when evaluating a particular cat food, but it is important to recognize the limitations. Talk to you veterinarian about the ingredient list and nutrient profile to help choose the diet that is right for your cat.

  • This article reviews the advantages and disadvantages of the different food forms available for cats, including dry, canned, and semi-moist foods. Dry food, or kibble, is easy to portion control and can be fed in puzzle toys. Canned food is a good option but more expensive than kibble and does not last as long once opened. Semi-moist foods are generally not recommended as the main diet due to their high sugar and sodium content, as well as difficulty with portioning. Feeding a combination of canned and dry is recommended for young, healthy cats so that they are exposed to a variety of textures.

  • Eclampsia in cats is a rare emergent condition of hypocalcemia that generally occurs one to four weeks after giving birth but can occur before. Risk factors include a poor diet, abnormal parathyroid gland, and calcium supplementation during pregnancy. Signs of eclampsia start as restlessness, panting, and stiffness and can progress to disorientation, tremors, inability to walk, and convulsions. Treatment includes intravenous fluids, careful intravenous calcium supplementation, and other supportive medications followed by oral supplementation and weaning kittens as soon as possible or supplementing their diet with milk replacer.

  • Many veterinarians, including nutritionists and behaviorists, believe it is important for dogs and cats to express their natural foraging and hunting behaviors. For pets living indoors, this can be difficult, and the lack of this stimulation can sometimes lead to behavior problems. Enriching a pet's environment with food toys and puzzles at mealtimes can fulfill the need to forage. The use of toys, puzzles and other novel methods of food delivery can also be effective ways to increase daily movement in overweight or inactive pets.

  • Esophagostomy tubes are placed through the skin of the neck into the esophagus to enable ongoing nutrition in cats that either refuse to eat or are unable to chew and swallow food. A diet will be recommended by your veterinarian but must be liquefied with water before it can pass through the tube. Medications can also be administered through the tube. Step-by-step instructions are provided. The decision to remove the tube will be determined by your veterinarian.

  • The goal of feeding growing kittens is to lay the foundation for a healthy adulthood. Portion feeding is recommended to maintain a good body condition. Proper nutrition is critical to the health and development of kittens, regardless of breed, and it directly influences their immune system and body composition. An optimal growth rate in kittens is ideal; it is a slow and steady growth rate that allows the kitten to achieve an ideal adult body condition while avoiding excessive weight and obesity. Growing kittens need higher amounts of all nutrients in comparison to adult cats, but excess energy calories and calcium can create serious problems. Preventing obesity must begin during the weaning stage and continue through to adulthood and old age. Together with your veterinarian and veterinary healthcare team, you can help your kitten grow into as healthy of an adult cat as possible.

  • Over 60% of cats in North America are either overweight or obese, so paying attention to the balance between activity and calorie intake is important. Nutrient formulation and portion control are the two most important aspects of weight control. Once you have chosen a formula and have calculated a reasonable daily portion based on calorie density, the best way to stay on track and prevent unwanted weight gain is to combine portion control with regular, formal weigh-ins.

  • Mature, senior, and geriatric cats often require different nutrition than adult cats due to their changing ability to digest nutrients and underlying medical conditions. Senior diets vary widely in nutrient profiles as there are yet no established standards. Recommendations for senior cat diets need to be based on clinical examination and discussion between veterinarian and owner. It is very important to ensure adequate water intake for senior cats.

  • Dogs and cats have different nutrient requirements, which is why separate commercial pet foods are made for each species. Even pets of the same breed or body weight have unique calorie needs, so pet parents should feed them in separate bowls to avoid having any pets gain or lose weight. Diets designed for young growing puppies or kittens are different from adult dog or cat foods, so pups/kittens should be fed separately from adults until around the age of 11-12 months. Body condition scoring should be a part of regular monitoring to make sure each pet does not gain (or lose) weight.
