It sound likes you're going great with your cat so far. I guess you should keep on doing what you been doing all along , if your cat is not moving around as much you may want to keep an eye on his weight and see if you have to adjust the amount of food you feed him. You want to keep his weight at a healthy place so his little heart will stay healthy . and Welcome!
We do have a huge addiction for photos of people pets . Hint Hint!
