Are there liquid meal supplements for senior cats?

I don't know of any liquid meals, but in the past I have given my elderly cats beef or chicken baby food. They usually like it right out of the jar. If not, try warming it for a few seconds in the microwave.

Liquid Meal Supplements

Hm this is a tough one. I recognize that your cat definitely has different needs than kittens, because the kitten supplements would make your older cat intensely fat.

I did a search and found this, but it's not liquid:

I never heard of it before, and before you give your cat any product like this you should still consult your vet to make sure it's OK.

Try the milk they have for kittens

Try baby formula (for human babies). Get powdered in a can to save some money.

I am serious.
