I thought at first it was hairballs but none came up. Then she started wheezing very heavily and making a honking noise at which time I made the vet appointment. I was very worried when it changed from "hairball" to "gasp for breath". I had to wait about 2 weeks to get in and she just got worse in that time. By then I was pretty sure because I had another cat several years ago who was asthmatic.

The only time she's had issues since has been when she was around a cleaner. I'm going to have to use unscented cleaners from now on. Event lemon juice is a problem. I need to stock up on vinegar and baking soda.

I hope this helps a little. Let me know if I can answer anything else. Poor London. It's no fun to be a sick kitty.
