Help with plastic allergy

My older niece wanted me to ask about this...

One of her kitties has a bad plastic allergy. She has switched the food and water bowl from plastic to ceramic and that has helped greatly but there's still a problem with the litter box. I can't think of anything she can use for that which is not plastic .... any ideas?

you can use a rubber drip pan, or even a large feeding bowl that you feed horses and calves in. Must be a bad allergy if the cat is allergic to their litter pan!

This could end up being expensive but how about a metal cake/bar pan. It will rust however.

How about making a wooden pan or box? You can line the bottom with a rubber mat to prevent humidity seeping into the wood and then change it regularly with the litter.

Thanks for the ideas MA, Gail and Yayi I'll pass them along to my niece.
