Orphaned kittens will need extra care for survival to compensate for the loss of their mother. Kittens must be kept warm, very clean, and fed frequently using an appropriate amount and type of formula by bottle or less often tube feeding. To ensure nutrition is adequate, daily weight checks should be performed for the first 4 weeks, then weekly thereafter. Kittens must be stimulated to urinate and defecate. Environment, feeding instruments, and the kitten must be kept meticulously clean as they are more susceptible to infection than kittens cared for by their mother.

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.

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.
