We recently moved monty to a much bigger cage because he was getting a bit cramped and starting to bar chew. Everything was ok for a couple of weeks but he's now started frantically bar chewing high up on one corner of his cage and also on his door. He really tries to squish his head through and it worries me so much .
To attempt to protect him I made a barrier out of cardboard which he promptly started chewing through. Then i put a hanging bird toy across that corner to try and restrict access but he just squeezes through it. I've now stuck a cardboard tube across one corner but he's pulling that down too
I feel like i'm doing something wrong but don't know what-he has chew toys, a large cage, cardboard toys, a good sized wheel, an hours playtime out every evening, i hide bits of food for him...and yet all he wants to do is climb up to the same bit and repetitively try and squeeze out. We have spent literally a couple of hundred trying to keep him happy, I'm so frustrated. To make it worse, he managed to open his cage door (and this is a rat cage) and then nipped me when I ran to save him from falling. When we go to bed I don't think he does it so much because we hear him on the wheel.
Basically I'm tired of worrying he'll get brain damage, I can't afford yet another cage and anyway I don't see how we could enrich his life any more than we are already-and all he wants to do is bar chew anyway
he's sitting staring at where he chews now which makes me worry he's already got ill from doing it.
Anyone been in a similar situation? Advice would be appreciated as I'm totally confused as to why he is doing it
