There are many brands of cat food that you can buy, This should be a trial and error. Buy different brands recommended by your veterinarian and for your cat's age. Note that these brands are expensive but will contain the full range of nutrients needed to satisfy your cat. A good compromise is to purchase dry food in this range but to choose supermarket brand wet food. This makes a nice balance without breaking the budget. It is also good to not grow a fussy cat!
Try to get a price is cheap and reasonable for its size. Look for the bargains on larger or smaller sizes and compare to make sure you are getting the best deal.
Feed your cat about 40 pieces (of dry food) in the morning and 30 pieces (of dry food) in the evening. If you can't be bothered counting that, it is about an adult handful. You cat will help you to gauge the amount it needs by displaying signs of overt hunger if you under-do it. Do not overdo it or you well grow a fat and unhealthy cat. Did you just buy a kitten? Maybe you want to add a kitten to your family? Kittens are cute, frisky, playful, and a lot of fun for children and adults, but they are also a lot of responsibility. Your kitten will need twice the nutrients of an adult cat and the best feeding routine is to feed the kitten 4 times a day. Once a kitten turns 3 months old then you can just feed them 3 times a day until they turn 6 months and then you can lower their meals to twice a day.
