How can I stop my cat pooping in the bathroom sink?

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?

    I’ve never had this problem, but here are a few ideas:

    1. You could keep an eye on her and spray her with water when she starts to use the sink, but you’re probably busy during the day.

    2. I don’t think the cat will understand why you are putting the litter box in the sink, so I wouldn’t try it, especially since it probably won’t fit.

    3. Try leaving some water dripping from your sink’s faucet. Not running, just dripping. That might discourage pooping there because she will want to drink the running water and won’t want it to drip on her when she is trying to go.

    4. If all else fails, try taping over the sink with duct tape when you aren’t home and see what happens, or try new cat litter.

    Stick the litter box on the sink so she has to go in it.

    Don’t worry, they usually "get it" after a week or so, and you can move the box to where you want it. Until then, she has to realize you want her to poop in the box too.

    You may need 3 boxes. Some cats are picky that way.

    Try a different litter in the 3rd box. Again, some cats are really, really picky.

    They’re just telling you how much they appreciate everything you do for them.

    Monitor your cats 24 hours a day and spray them with a water bottle when they poop in the sink. Or put your litter box on your sink. Hopefully you don’t need that sink for anything else, like brushing your teeth, washing your face, etc. Have you considered buying a bigger house so the cats can have their own bathroom?
