I use one very similar to that one for Nova. It cost me $10 at Petsmart. I only use it because she digs though, I don’t know if it prevents flinging of poop. I also have a high back one that I also got from Petsmart for $6 for Hubble, also a cat box that I think would maybe work better for you. Nova is pretty light on her feet so when she jumps most of the stuff stays in place, but Hubble is clumsy, heavy and awkward and when he jumps things hit the back of his litterbox. I think it would depend on the type of litter you use as well. I use Yesterdays News, so it’s heavier than some of the fluffy paper stuff, but maybe not as heavy as some litters.
Hubble’s is similar to this, but it doesn’t have the heart shape and it’s bigger (plus it’s less expensive!). This pan is rather small and I wouldn’t recommend it. http://www.petsmart.com/product/index.jsp?productId=3120660
I don’t have this one, but it looks like it might be good.
