Why is my active cat suddenly weak, sleeping, not eating, and cut?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 5 lbs

hello, recently my cat has been sleeping all day and having random cuts appear on him. at the moment he has a cut on his bottom lip. It cannot be due to fighting because he stays inside and sleeps all day. He used to be a very active cat and begged to go outside so it is unusual of him to be acting this way. He seems to be very weak and only gets up to eat very little of his food. What could be the problem?

Thanks for using Petco Pet Education Center, formerly Petcoach! I'm sorry to hear Kitty isn't feeling well. I would recommend he be evaluated by a veterinarian to determine what may be causing him to feel ill. Lethargy and weakness with skin issues may be due to a virus, an infection, an autoimmune disease, or another underlying issue. I would have him seen, have any necessary testing done (bloodwork, X-rays) and get started on any treatment he may need to get him back to his old self! Good luck!
