Depends, if I've accidentally stepped on a foot or tail the cat gets picked up and cuddled as I check to make sure the cat's ok. This is mostly just to let my boys know I wasn't actually after them in some way.
I don't know if they can put together you giving them a treat as apologizing exactly. Animals do not apologize to each other. Maybe just as getting in their good graces/sucking up.
Oddly enough, i never thought about that! I'm not sure he would really like or know what to think of me picking him up off of the floor but i sure will try!!
Thanks again! you (us, now) "cat" people are the nicest! hehe
