daughters cat sick

Question
   hello, my daughters cat ,which is a year old was fine last night but is all whobly ,can't walk up stairs& seems to be breathing heavy.Also his mouth sort of hangs open,our vet is not open where its sunday, & can't really alford to take him to 24 hr place, any ideas what could be wrong, do u think he will be ok till morning when i can take him to our vet?  thanks so much

Answer
I'm sorry I didn't get to read this question until morning. This sounds like an emergency -- please call your regular vet immediately. It could be any one of a number of things, all of them serious, and all of them requiring a vet. This isn't the kind of thing a service like this can help with.

I'm sorry -- I hope you can help him.
