Couldn't believe it. I was stood there having one myself (not in the sink) when kitty jumped up into the sink and started to relieve herself.

I mistake the sink for the toilet sometimes when I come home drunk...

My cat dosent drink.

Are you sure? Maybe your cat goes out when you sleep?

How did your cat manage to urinate?

Does he have a litter tray? Was it clean? Cats can be fussy and if things aren't to their exacting standards they can seek relief elsewhere.

Also is the drain of your sink nice and clean? Maybe it whiffs like a cat loo (and thus reassuring for that purpose)?

I've experienced my cat peeing on the carpet, right in front of me. He came tearing up the stairs one day (from outside) and did his business in front of my startled eyes. It turned out he was in a turf war with another cat and was being bullied, i.e. upset.

We've just moved into a new house & she's not too keen on facing upto the local cats at the moment. What she usually does is wait for the dog to go in the garden then follow him out, do her business then run back in again. We do keep her in some nights so she must be bursting in the morning, i was just so shocked when she did it.
It was a bit weird but i suppose it was good she didn't go on the carpet. A litter tray would be a good idea for the nights she stays in, unless we can teach her to flush.

Squatted.

Both my cats have the odd wee in the bath if I haven't changed their litter quickly enough- I guess it's their version of a dirty protest.

Was it a proper wee? When mine had a urine infection, she tried to tell me by squatting over the plug hole in the bath. It was only a tiny amount and I presume that she was trying to see if the coolness relieved her problem. When mine is having problems with other cats outside, she ignores her two perfectly clean and unused litter trays and finds a carrier bag to pee on. Bless her, at least I am not having to clean it off the carpet!

Mine do that in the shower tray. Well, twice. Both times because their litter box needed cleaning out.

I'd much rather that, than on the carpet though, as it's so easy to clean up!

Yep my tinker likes to wee in the bathroom sink she only does it when her nemesis from next door comes and annoys her !

I'd be delighted if my two tinkers always pee'd in the shower tray. It would save me lots in cat litter (they don't go out). I'd want the lumps in the litter tray though!

Ewwwww

you have seen this happen now..how many times has this happened before..just before you shave,wash your face,clean your teeth!!!

What about your itchen sink..how do you know she hasnt done it in there either..
I would put some of that get off stuff for your garden in both..cant be hygenic.

lol that's sooo funny.

probaby because it STINKS if you don't rinse it out
