I use Natural Chemistry Healthy Habitat to clean his cage and I live with a roommate who owns the house, so no one ever comes in to spray pesticides in my room... In fact, I'm pretty sure there are no pesticides or anything beyond Pine Sol being used anywhere in the house or vicinity of.
The last time his temp could have gotten that high (I estimated it got to that temp because my room gets hot sometimes) was during the summer. It usually stays about 80-85, lowest I've seen is 77. He's never had mites so I've never had to treat him.
As far as I've known, he's only fallen once and that was yesterday when he spasmed when I had to take him out because he got his towel sopping wet overnight and he landed in the litter box for 2 seconds on his belly (he's on aspen now in the 40b).
Vet didn't do an x-ray or even suggest it (her and the vet tech were pretty scared of him because when they told me to put him on the ground to see him move, he struck at her once).
I don't smoke and no one in the house smokes, plus his breathing looks normal.
I fed him yesterday and he ate perfectly fine, just like normal.
I've had him.... Since roughly April 2018. So about 9 months.
