cat not itself since being in a cattery

Question
Since my 1 year old male cat Theo spent 2 weeks in a cattery its been sleeping a lot and not eating much and seems too have trouble jumping and getting down and I am now getting worried its been 3 days and seems to be getting worse.

Answer
I am not sure what you are asking me. Why was he in a cattery? Are you talking about a breeding facility? That is what we call a cattery here in the USA. It sounds as if he is harboring some kind of injury to his back or his legs.

In either case this is something a vet needs to see and feel with his own hands. This is not something I can help much with online.
