oh man!
I am so sorry about the bad news!
I would hope all of your friends understand about your priorities. We are all good people, at least the ones I know. I would do the same thing. I hope your kittie has a full recovery!
i'm sure everyone understands and that party is the last thing you should worry over.
poor kittlez. i do hope everything is ok. they can be so helpless and you just have to mother them.
