Reply #13: I had a similar situation

Years ago, our kitty Missy was a shelter rescue. Back then, they didn't always spay/neuter them so we had no idea whether she was or not.

She actually would back into things and rub against them. When it got to the point she was umm..how do I say this..setting her sights on Hubby..we took her to have her spayed.

The Vet called in the middle of the surgery, saying that Missy had already been spayed but they would continue to look for a piece of ovary. They didn't find any. Funny though, that behavior improved after that.

Although..she did have some other issues. I always thought it was the kids taking pens and pencils out of the pen cup until I found her at the top of the steps with them neatly laying in a line, like kittens, with her talking to them and treating them like kittens.
