An update: Our vet said as much that this could be a botched spay, that perhaps some tissue was left behind. I've called numerous times and left messages and e-mails, no response yet. They're strictly a foster-home shelter so I believe they don't have a central location or a live person manning phone calls. I'll keep working on them.

Since all our kittens were spayed early on I've never experienced one in heat, so it's been interesting to say the least. All day yesterday and today I was hearing a beeping-type noise and figured it was the smoke alarm emitting low-battery warnings. Being that I'm hearing-impaired, I didn't figure out until today that it is Abby! I heard the "beeping" and saw her mouth moving at the same time, oh ... she's meowing !!

The shelter is doing 3 Petsmart adoption days tomorrow so I'll head off to one of them and see if I can't find somebody to talk to.
