Look what my family found in our back yard. She started out as a friendly anonymous cat. Turns out that although she looked well-fed, she was hungry. Then we started to suspect that she's pregnant and got dumped for getting that way.
Anyway, we got her a collar, and we'll be taking her to a vet to make sure she's eating for more than one. Squirt's slowly getting used to her being in the back yard, but I don't think we should let them bump noses just yet, so Molly'll remain an outdoor cat for a while.
UPDATE: Seems Molly wasn't pregnant, just had a little pudge: She's already been fixed, so that's one extra bit of evidence for the dump hypothesis, though it pretty much falsifies the reason we had guessed as to why she was possibly dumped. Of course, the possibility remains that she's a runaway. Oh well.
