Give your cats some water! Geeze. Cats will go into kidney failure from a lack of water in like a single day. They wouldn't be doing this if they had access to fresh water.
It may also be they aren't trying to get water and they are trying to get at the mineral deposits left behind from the water that covers the inside of pipes and faucets, just like sometimes you may get a craving for something salty.
If I had a cat and caught it doing that, I'd absolutely turn the faucet on.
Stop trying to deepthroat the water delivery system, dumbass.
Why?
Is it unhealthy or in what way do they hurt themselves trying to gather fresh water?
Maybe just put an attractive alternative somewhere, like a cat water fountain?
I’d be worried about my cat chipping a tooth again, but she’s also a bit of a dumbass.
They'll turn into water balloons and then I can have a water balloon fight.
Edit: I also kinda prefer my water without toxoplasmosis gondii.
My cat refuses to drink water from a water fountain 🤦♂️
If you want them to stop, don't encourage them! Only turn it on when the tip is in.
