I caught Tycho yesterday going to the bathroom somewhere he shouldn't - plus it didn't look like it was going so well. Tiff decided when she got home that she needed to call the Vet, and they told her to bring him right in.
Well, it looks like he's got a UTI, so they kept him overnight. They gave him a bunch of antibiotics. This morning he still hadn't gone to the bathroom despite eating and drinking normally, so they have to put a catheter in him which means he'll have to stay til Monday.
