I just made my pig a C&C cage and he seems very happy. His old cage was waaaaay too small. I made him a 2x3 with a 1x2 loft. The loft is made out of leftover coroplast and a slab of carpet. While he loves the ramp, he keeps chewing on the carpet. Is this bad for him? I just don't want him to get sick. Also as I was watching him today, he started chewing on the hammock that I put in them. He likes to sit in it but also chew it. I just don't want him to get sick from these things. He has food in there so he shouldn't be hungry. What should I do?
