My cat had kittens, two of them. The father of the kittens is a manx. One kitten died of FKS or whatever. But the other is still alive. His name is Lil Dude, and he is deformed. His nose is turned up like a pig's, he has no tail, his abdomen is abornmally large and swollen, and his back two legs are a tangled and paralyzed mess. They look like they've been stepped on and flattened and he drags them around everywhere. But that's not what I'm concerned with. His swollen abdomen is. I noticed that he wasn't pooping (he's almost a month old) and figured that was why his abdomen is swollen, so I started wiping his butt with a warm cloth. Fortunately, Lil Dude started to poop and his abdomen is no longer as firm and swollen, it's softer now. But..his butthole doesn't close? It's just a constantly opened square-ish looking whole. Does he not have the muscles to close it? Please help. I don't want Lil Dude to die but I have no clue what's wrong with him!
