Nya has improved substantially. After 10 days of antibiotics, I got a urine sample by cleaning out her litter box and washing it. The vets gave me a sampling kit including a little bit of non-absorbent litter, a syringe, some instructions, and a collection bottle. So, I put the non-absorbent litter in the litter box and Nya peed in it eventually. I sucked up the urine and put it in the collection bottle, put a label on it (my idea), and put it in the fridge until I can take it to the vets. I'll soon find out the results of the urinalysis, but I trust that it will be normal because Nya seems normal. She finished her run of antibiotics today. Pushing a pill down her throat everyday was a two person job. My wife holding her, while I opened her mouth and pushed the pill to back of her throat. I timed the urine sample with the arrival of the new bag of pretty litter, so once I cleaned up the litter box after the urine sample, Nya got a fresh refill. I'm so glad she is all better. It's so nice to have a happy cat.
