So I have a Syrian named Fen, generally he seems quite happy but whenever I lay down in bed at night he'll chew his bars, I never really see him doing this when I'm at my computer.
In general he seems pretty happy, he runs on his wheel at night and I let him have (pretty much) free reign of my rather large desk with toys and a house with bedding in it.
I'm not sure if he's biting his cage because something is wrong or I'm not providing him with something, his food seems generally a good mix and I also feed him fruit like apple slices from time to time.
It really seems like he only bites his bars to bother me so I get up out of bed even though I get him out and hold him a lot before I go to sleep and in the mornings
any opinions on why he might be doing this would be nice
