I have been trying to convince my parents for a c&c and they think my piggies will chew on the grids and ruin all the fleece I put in it. They say my piggies are messier than all the guinea pigs who have c&c's with fleece. I try to tell her that all guinea pigs are pretty much the same with being messy and everything. She just doesn't believe me. Does anybody have any ideas for convincing?
