What food and supplements help a sick cat gain weight after illness?

Updated on September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Male | neutered | 5 months and 4 days old | 4.2 lbs

Watson has been really sick for a few weeks. He's on antibiotics, anti-nausea medicine and fluids. My question is what is the best food and supplements I can feed him to put weight on him now that he's up to eating on his own? He's essentially bones and fur right now.

I recommend feeding Hills a/d. It’s easily digestible, cats usually love it and it is very calorie dense so Watson will start to recover quickly even if he doesn’t eat that much. I would also have a dry kitten food available at all times and offer some tasty cat treats to stimulate his appetite. In addition to feeding many meals daily increasing his exercise will help build muscle and also stimulate his appetite and speed his recovery. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Watson.
