Urinary tract / white blood cell problems
First time 'real' poster here! Our cat was in and out of the litter box on Saturday night / Sunday morning. He seemed to be constipated, then all of a sudden he had diarrhea and started rubbing his butt on the ground. So we took him into the emergency vet. They did some tests on him and found some crystals in his urine, said that he had too many white blood cells in his urine, prescribed some antibiotics, and told us to switch him to a Medical Urinary SO wet food only diet.
We brought him home last night and he seemed to be getting a little better. He takes his pills no problem, he is eating the new food just fine, but today he is apparently (gf is home with him, I'm at work) getting worse again. He is meowing as if he is in pain when he pees, etc.
I know it has only been about 28 hours since we first took him to the vet, so he really shouldn't be magically better yet, but I also know this is a fairly common problem in cats. So I was hoping people on here might have some tricks to help him heal faster? I hate to see him uncomfortable and in pain.
I have heard that dusty cat littler can cause urinary problems too, and his cat littler is very dusty so I'll be replacing that ASAP.
Any other ideas? Anything is appreciated.
