I woke up at 5 am to the sound of one of the cats out in the porch. It was an odd, howling sort of meow, something I'd never heard before. I went out to find Puffball writhing around on the floor, panting heavily,and howling. He appeared to be partially paralyzed. I called the vet, left a message, and she called back. She said it sounded like a blood clot, and the prognosis wasn't good.
I'm bringing him in at 8, but I'm expecting the worst.
I have way too many cats outside that I want to get rid of.
