There are several ways to give your cat liquid food. If your cat is strong enough, they may be able to lap liquid food on their own.
However, sometimes after surgery or during an illness, your cat may be too weak to lap liquid food on their own. At times, they may also not want to eat anything at all, so you may have to force feed them.
In this case it may be necessary to use a syringe to feed them. Your veterinarian will show you how to use a syringe to care for a cat by giving small amounts of liquid food to them.
