Ok so my albino green burm I just got, makes a slight wheeze whistle noise occasionally maybe every minute if he breathes really heavy but u have to listen very quietly to hear it, he doesn't have any other sign o respiratory infection, and I took him to a vet but they don't do a lot of herps, but they said it might just be normal, prehistoric pets also said it's normal for some burms, anyone care to explain? I haven't tried to feed him yet but he seems strong and he does hiss a little when I first take him out but not after he's out that's what the noise sounds like a little bitty hiss/ heavy exhale, but he seems fine is this normal?
