Uggggh, London had gone about 48 hours without an episode, but he just had one. There's no wheezing, he just sounded like he was trying to bring up a hairball and had his neck stretched out. This episode lasted for about 3 minutes, then he jumped up into the window and seemed fine. After that, he fell asleep on the cat tree, but then he usually does nap at this time of the day. So it's been about 2 1/2 weeks since he started doing this. Every time he stops for a couple of days I relax. Then when he has another episode I feel like I'm going to get sick with anxiety. And he always looks at me with his big gold eyes as if he wants me to do something to help him. It's heart-wrenching.
