/diy/ - Do It Yourself

I have a large cat. He wont fit in any plastic litter boxes. His face hangs over one end and his ass over the other and he shits on the floor because why not.

I'm looking to build a custom litter box out of wood and I need to know what kind of heavy duty coat I can put on the wood that will be waterproof and durable enough to withstand cat scratching and wear from scraping with a metal scoop.

I was thinking of something like rhinolining, but it doesn't seem like you can just buy that stuff in a can.

THANKS
