Last Friday 7th my cat Max(4 Years old). Came in later than usual 7 pm through front door. He appeared very nervous. Walking around slowly and checking out as if he had not been in the house before.

He eats his food, if I take him to it.does not appear to be physically hurt did check him out. Help
Aloha! You're speaking with Dr. Michael Salkin
I'm sorry that your question wasn't answered in a timely manner. I have advanced training in feline behavior. We don't have many vets trained in behavior on the UK site at this time.

You're correct to consider Max's "experiencing something outside". That "something" is most often another cat and territorial issues have come into play. Territorial aggression - an actual altercation with another cat - as well as fear and anxiety as a result of that meeting are the likely causes of Max's behavior...which is not only expected but smart - he's not as likely to be hurt if he sequesters himself as he's done.

Max can detect another cat's phermomones - chemicals secreted and detected by other cats - and is likely to become more bold once the other cat leaves Max's territory. Meanwhile there's no reason for you to do anything more than be patient with him. A vet's attention is only needed if Max became inappetant or developed symptoms indicative of illness.

Please respond with further questions or concerns if you wish.
