We have two kittens, a brother and sister, about 4.5 months old. We’ve had them for about 2 months. For the past week or so, I believe it’s the female kitten who’s been pooping in the bathroom sink! Both of their litter boxes (which are cleaned daily) are in that room only feet away. Last night I tried putting a paper plate in the sink with food on it because I read they will not "go" where they eat. But she ate the food then pooped on the plate!
I’ve thought about filling the sink up with water or trying to block it off completely … though I’m afraid that could possibly trigger her going somewhere else. Any insight or suggestions?
