Our rescue cat has been with us about 6 months now, we were on holiday recently and put him in a cattery. All seemed well, the cattery owner said he was absolutely fine. Since coming home he seems confused and on edge. When he first came to us it took him some time to feel safe and not be jumpy all the time, but he seems to have regressed a bit. He's had lots of attention and strokes (he's told us to stop a few times!) And he's had treats and we've left his fave spot by the fire free for him to use. He's been around the house smelling everything but is very jumpy and unable to relax - he used to sleep at least 20 hours a day. Is there anything else we can do to get him to forgive us for going away?
