Have you ever tried Zithromax for kittens? A few years ago I had a nine year old mama cat from an idiot nearby, and there were 7 kittens. They were about 5 weeks old when they started to get very sick with probable pneumonia. It was Sunday, of course and I gave the one that was on his way out gasping and almost to the point of no return, a tiny chip of Zithromax. The others also, but within 12 hours the little guy was up and feeling back to normal! I have used it with great success with other tiny ones that start getting that terrible congestion. http://www.users.bigpond.com/drdavid/zithromax.htm Here's one site I've found a while back regarding Zithromax and kitties. The liquid is easier to use if you have a number of sick kitties, but the drawback is it's only good for 10 days. I keep a few tablets on hand for kitties here.
