Thank you very much for the replies. I'm glad that I asked.
I have neomail turned off because I got tired of the begging messages, but I'll put it back on in case someone is trying to reach me.
It makes me sad that someone might have tried to make it more adoptable and then put it in the pound. I've got to remember this is all a game and not real.
I put a pet in the pound once after getting it all fixed up, and I left the petpet that I'd given it with it. When I checked later to see if someone had adopted it, it had been, but the petpet had been taken from it.
