I'm so sorry to hear about your poor kitty! I will say a prayer that he makes it through okay.
I can totally feel for you--We lost our kitty Lily a couple months ago when she got out and my parents' dogs killed her.
I was and still am devastated. I just had a good cry tonight after viewing a youtube vid of a yorkie and a white kitty playing that looked just like my Lily..she was Bella's best friend, and she still looks around for her.
I pray your feline baby makes it through with no complications at all <3
