Food recommendations, such as what to feed your kitty and when, should come from your breeder and then ultimately from your vet. There is a great cat resource online written by a California veterinarian, Lisa A. Pierson, DVM, that addresses the dangers of a dry food diet. Decisions about what to feed your cat, which brand of food and what type of food are something that you will have to come to terms with based on your budget, your lifestyle, your living situation and your vet’s recommendation (and whether or not you trust your vet or if you think s/he is being paid by the large pet food companies to sell product). You might also find this page on Liz Eastwood’s blog, The Natural Cat Care Blog – The Best Canned Cat Foods, helpful.
Keep in mind that the recommended food quantities on pet food containers are based on the amount needed by active cats living in multiple cat households and the amount needed by sedentary, neutered or spayed cats is often much lower. You’ll want to seek your veterinarian’s advice as to the type and amount of food to feed your cat.
Remember that cats in the wild eat many small meals per day and smaller meals more frequently might help you avoid problems with obesity later on.
Be sure to monitor eating habits in the first week. You’ll want to continue the food regime that the breeder or your vet recommends. If you are switching their food, you have to do it slowly to prevent stress and diarrhea.
So no matter if you want to switch your kitty from the food the breeder was feeding to something else or not, be sure to have some of the food on hand that the breeder was feeding your kitten. They will recognize the smell and eat it. If you decide to feed a different brand, gradually mix it up to 50/50 with your kitten’s previous brand for a week before switching over to the new brand. This way, your kitten’s body can adapt to a different diet. Be sure the brand you switch to has low or no by-products and is high in protein for the best health of your kitten, especially in the first year of growth.
