You sound like me, only I have 5 cats and have no idea who is doing the "plops" in my living room. ONLY the living room. Only in one area. And they are big loose plops.

I had thought for months it was RIP Honeybun, but he's not here anylonger, so I know now for sure it's not him. Now I have to figure out who it really is. I'm soooooo confused. Normally it happens when I go away on the weekends, or for an extended vacation during the summer months (I'll go camping for a week at a time). So I figured then it was separation anxiety. But now, it's happening during the week when I'm here at home, so it shouldn't be separation anxiety, should it?? I mean, I work, but I'm not going to quit my job just to make the cat happy and not poop, lol.

It's just testing every limit of my sanity to not scream at them to stop pooping and knock off the behavior, like I'd want to do with the kids at school, lol. Not that they'd listen or understand (like the kids at school, lol). These cats are just driving me up a wall. I THINK it's Sophie, but I'm not sure. Part of me says maybe it's my new guy, but it's been going on WAY longer than he's been around. So maybe it's not him. SIGH... I dunno. Sophie was a pooper out of the box from way back, so she's the first one who is coming to my mind. It's just so frustrating. And I can't afford a video recorder to see who is doing it. We tried a night vision camera, but came up with too bright picture of every cat in the house, and none of them pooping, lol. OY.

I have used every food under the sun, and it doesn't seem to matter which one I choose. Right now they are all on Blue Buffalo Sensitive Digestion. I want to get California Natural, because it worked best in the past, but I can't find it anywhere around here. It's driving me nuts as well.

Good luck and hope we both find a solution!!
