My Cat Seems to have a cold

From what I read I take it she's drinking and eating all right? Just a bit stuffed up. That can happen. Cats can get colds just like us. Try putting a little vicks or bengay on the tip of her nose. Not much mind you just a dab. The menthol will help break up any congestion. Check and make sure that her nose isn't blocked with any nasties first. You may have to wash that off to clear the nostrils. Our vet also recommended using a human decogestant nose spray. We use the one that says "Nasal Deognestant 12 hour spray with Oxymetazoline hydrochloride". I believe it's the generic of Afrin. Just try to get a couple of drops in the nostrils (forget getting it to mist up there. Just a drop or two will help) I doubt the a/c on it's own did it. She probably just caught a cold. If she stops drinking and eating or becomes listless try and get her into a vet. See if there is one that will allow you to make payments. I do understand how going to the vet isn't always an option. I know I've been there myself. If you can call around now before hand so that way you have one for just in case and perhaps check with a friend who might be able to drive you.
