That is disgusting- what if your customer sees that you are using cat litter ?! Use play sand that you can buy at Toys R Us, or just use a water balloon. The cat litter is probably tearing the latex.

Hi April,
Well, I wouldn't call it disgusting to use (fresh) cat litter, but I agree that the cat litter causes the problem. I am not sure but I could imagine that there is some sort of substance in the cat litter that doesn't go well with latex and causes the balloon to deflate. Tearing could be a problem as well.
As said in the other comment, using play sand or water should solve the problem.
