I heard there is a kind of litter that does not absorb? Does anyone know if this, what it is called, do I have to get it from the vet? I am taking pansy in on Friday, and I want to avoid the needle into the bladder for Pansy and my wallet. It is hard to get a sample from Pans, since he only pees in front of me if he is having a problem, and then I can only get a few drops, because he is having a problem. If I syringe him water, he has good pees, that and many other things we are trying. It alleviates the problem, but I want to see if there is an infection.
