My cat had 5 kittens 3 weeks ago. All are doing well but this morning, the most boisterous of them (a boy) raced towards me as I entered the room and, well, fell off the bed. There was a thump and although he's one of the biggest I'm still worried... So far he hasn't shown any odd signs... as soon as I gave him back to his mother, he started drinking as normal. My only concern is that he's not playing as enthusiastically with his siblings any more. Has anyone had any experience with something like this? Any help would be appreciated!
