You should read the instructions on your chosen cat food for detailed information on how much you should feed your cat. You will also need to change the amount of food for kittens, adult cats and senior cats, so make sure you take this into consideration. For example:
Kittens Kittens have small stomachs and high energy needs, so they need to be fed little and often. Remember to check their food and replace it four times a day. It is imperative they are fed specific kitten food which provides nutrients required for growing and is more energy dense.
Adult cats Your cat is an 'adult' when they are between one and eight years old. Your adult cat needs to be fed once or twice a day, but some will regulate their food intake, so their daily ration can be left out, particularly if you give them dry food.
Senior cats Cats over eight are considered 'senior'. As your cat grows older, their nutritional needs change and you can buy special foods that cater for them. These foods may have less protein and a balance of minerals and vitamins designed to keep them in good health.
