a few lines further down i said that my cham started the funny behaviour of taking hour long showers under its dripper.
now he got very inactive (he's shedding) but what concerns me is that he has his mouth open a tiny bit and his nostrils are clogged. he also gapes from time to time. what clogs his nostrils is not the white stuff (exessive minerals)but it's rather yellowish.
i now cleaned the nostrils with lukewarm water and cotton swabs. funnily he turned to very light colors as i handled him.. usually he gets dark/annoyed. doing that i looked into his mouth and it doesn't look good in there. parts are yellowish / brownish and it looks like an infection
am i dealing with an URI here? how concerned do i have to be? what are the steps that have to be taken? can i fix it here or need i go to his vet (knowing what it is)?
thanks for your advice.
