So I've only had the guy for 2 weeks, and he doesn't normally but he usually hangs out with me but if I move suddenly or I pick him up, and I guess he's not expecting it, he lets out a little whistley kind of wheeze. He doesn't do it normally or if I'm handling him slowly, and it's happened maybe twice, but I thought I'd post about it just in case it's something. Took him to the vet not too long ago (three days to be exact) and she said that he was breathing normally. Had him checked out specifically since his previous owner was a heavy marijuana smoker and she said that everything seemed normal, and he does seem normal for the most part. Should I be concerned?
