My 5 1/2 month old sisters, Charlotte & Bridget, were spayed Wednesday. Charlotte seems to have handled everything just fine. Bridget had a slight temp Wed. a.m.; the vet attributed it to stress, so waited a few hours to do her surgery, when her temp was back to normal. She had a terrible time with the anesthesia afterwards---clawing at her mouth, shrieking, scratching---scared the bejeebers out of me. After a couple of hours she settled down & seemed ok. Thursday I noticed she was in & out of the litterbox more than usual; late in the afternoon she began sitting in it for several minutes at a time, straining. It was just before closing time when I called the vets. He didn't think he needed to see her, but wanted me to come pick up some antibiotics for her. So, she's had her Clavamox 3x so far, and doesn't seem to be in the box quite as often. I've had a lot of experience with cats & UTIs (unfortunately), but I'm wondering if this is just something that happens after a spay. It's been 17 years since I've had a kitten spayed, and I don't remember anything like this happening. Could this just be a coincidence? I know I'm probably worrying way too much about this, as Bridget is acting pretty normal otherwise. Any thoughts or advice would really be appreciated.
