Pet's info: Cat | Mixed Breed | Male | neutered | 1 year and 11 months old | 18 lbs
killian was happy and very friendly until 3 days ago. He suddenly has turned into a withdrawn cat, not wanting any contact with anyone. He is an indoor cat, no visitors came, nothing strange happened. He lives with me and 3 other cats, two females his age and a male who is 5. He eats, can run and jump, but stays alone under a chair... Could it have been a fight with the older male? Or is he sick? What can I do? Thank you.

Hello. It does sound like some event occurred to him. You indicate he is eating, which is good, but are you sure he is using the litter box, especially urinating? If not, this might be a concern. Sometimes when there is a personality change, it is best to first rule out the possibility of an underlying illness or injury. If he is eating & you are sure he is having no difficulties urinating, just watch him over the weekend, but consider having him examined sometime next week if he still seems off. Thanks for using Petco Pet Education Center, formerly Petcoach.
