look up a video called "reverse sneezing Tapioca" on YouTube or Google Video and you'll see a Siamese doing something pretty close to what Havoc does. He doesn't go that long though. And he almost always sneezes normally a few times first.

I'm guessing if he had allergies that the antibiotics wouldn't clear it up, right? I use Tidy Cats litter, which is the least dusty I have been able to find.

I looked up feline asthma and from what I see the symptoms are more along the lines of coughing, turning blue, etc....not sneezing. Can't say I've seen him coughing per say. Seems more sinus-related to me

I know URIs are pretty common in cats, but they're pretty contagious too and Toby only started sneezing once and was perfectly fine 2 days later.

Havoc finished up his 3weeks of antibiotics on Labor Day. He's starting to get a little snuffy again. Poor thing, I guess I'll take him back to the vet in a couple days, just gotta figure out which one to go to.
