Hey I just picked up mojo after he ate(waited the two days of course) and upon picking him up I let him chill around my neck while I went to do something and I heard a hissing noise. Now I heard this when I went to pick him up also and just figured he was saying hello to me. But putting him up to my ear I can it like 3 times in less then ten minutes. I am going to wait and see for one more day before vet but should I increase humidity or decrease it for the little guy in this case?
