I picked the husband up from work when my training shift was over today to take Chico (pictured above, with Molly, who is only a year older but twice his size) to the vet. They poked him, they prodded him, they updated his vaccinations, then listened to his little heart beating, took an ultrasound of his kidneys and stole the urine right out of his bladder with a large needle.
A hefty vet bill later and I have to bring them a stool sample because they suspect he may have a virus, but were very vague about exactly what sort. Apparently, they found bacteria in his urine and his white cell count is off. They sent us home with drops to hopefully clear that all up and several recommendations to help us keep him from using the carpet outside of his litter box as a litter box.
They said the fact that it's been about 6 weeks since we moved and he's only peed in the apartment twice and only in the last two weeks, doesn't look like trouble behavior, especially since it's been happening near the box and he isn't spraying, just urinating. They said it's possibly a combination of the new litter we tried and an infection, probably caused by the litter. They also said it could be that I don't feed him enough wet food. Apparently some cats don't digest dry food as well as others and I probably have one of them. As if my cats aren't spoiled enough already.
So, I'm a bit more hopeful right now. I'll be paying several bills late, but for now I get to continue to love on my cat and enjoy his company.
