Can Chewing Corex Harm Piggies

[karenben]

My piggies have taken to chewing the corex sides to their cage and appear to have eaten quite a bit. Can this harm them?

 

[Stewybus]

Mine do, especially the boars but it hasn't harmed them so far. It may be good for there teeth.

Mine do this and it irritates me, I have given up so to speak and wedged cardboard in between the C&C and the correx and they are now nibbling on that, at least it is better than the correx.

One of my boars does this, he chews everything but Correx is a favourite and I've been quite worried also. Although he's always been fine and healthy
