Behavior Cage Biting

Maybe if you pick her up before you go to feed her it will help? My Sheldon was always bitting and tugging on the grids when I had to put up a divider due to bloodshed. I was always worring about him breaking his tooth. The grids aren't made specificaly for piggie cages, they are sold as storage cubes in stores, hence the plastic coating.
Most piggies will poop where they sleep so if they are sleeping in the cuddle cups there will be poop. Your lucky if that's the only places they are going. I just introduced my neutered boys to their respective girls and now I have 2 cages that have "beans" covering every inch of the cage. I hope after they finish marking and figure out who is boss pig they will start using the corners again.

I never thought about it, but I guess it does reinforce the habit. Izzy bites the bars habitually before it's veggie time. Only when I've got veggies mind you.

I know there really isn't a way to stop it, but I don't want to reinforce it.

And well, they are manufactured for cube storage Not gp cages.

I understand what you mean about the litter box thing. Felix pees in every hidy. There's a reason I have so many. I have to switch them out constantly.

Mr Whistles used to chew his cage bars alot. I wouldn't worry about it.

I'll try picking her up or not giving her the food when she's biting. @Hhbean that's the thing! They're not sleeping in the cuddle cup at all My piggies specifically go into their litter box to go to the bathroom, the poop just piles up in there! Haha! And I actually see them walk all the way to the litter box, jump in, pee, and then jump out! It's really amazing, I just wish they didn't think the cuddle cup was another litter box! It seems they do the same thing since I never see them in it
