I'm with Cindi. I'm not saying don't exercise with him...but I'm not sure how much you moving him around will do. As he feels better, I think he will move around more. I encouraged mine to play with a bird on a stick toy (they adore it...my little one will take it in her mouth and walk off dragging the stick behind her...and the others will chase her and pounce on the stick!). We also used a laser pointer that only Gypsy loved. If you can entice him to play, he'll enjoy it hopefully and it might help him feel better too.
