i hope this is the right thread for this question; apologies if it's not!
so he's a healthy-and-eating 2 year-old and he's starting to act out of the ordinary: i'll come home and see a giant lump underneath the bedding and realize he's made his way underneath his carpet. at first i thought he was cold - trying to get closer to his heating pad beneath the carpet - but after obsessively monitoring his temps for almost a week i've found no change (air temp never drops below 75 F, his UTH for the warm hide is around 89-93 F and works fine) and have noticed he tries to stretch towards the cool hide (not staying on the warm side).

so last night as i go through this routine of pulling him out and fixing his enclosure i noticed something: while fixing his viv i set one of his hides on my bed, letting him go into it, i noticed he stops trying to go inside when his body is about half-way through. that's when my my second hypothesis came: is he too big for his hide/enclosure and therefore not comfortable in them? the enclosure is 20 inches long, i believe (i'm at work at can't measure) and has these hides in size large. he's probably over 3ft.

after setting his viv back up and placing him inside towards his cool hide, i noticed he did the same thing: stopping when his chunky bits are half-way through, and sloooooowly going in. any other ideas? i was already planning on getting him a bigger enclosure in a month or so but i might have to make that sooner than later. any insight or advice is very appreciated! thank you guys!!!
