Haha! I've told this story before about my childhood cat, Smurf. She was a stray that we'd taken in. My mom wasn't much of a vet person. She's more of the "if it aint broke, don't fix it" type. Anyways, I think we had Smurf for about 5 years or so before she contracted FIV. When we took her to the vet to be put to sleep, lo and behold, we found out Smurf was actually a neutered male. I think we were so in shock about it that we hardly even mourned her death. (See, to this day, I refer to Smurf as her. lol. Or sometimes when I think about it, I call her IT. I can't bring myself to refer to her as a he.)
