Smell of cat wee but no cat!

[DtPeabodysLoosePants]

Hi, my kitchen/dining room smells of cat wee but we don't have a cat. I've mopped and mopped and used bleach but it still remains. A neighbour's cat sometimes comes in to say hello but isn't left alone and there's never been any cat wee anywhere so I'm baffled as to what has caused it and how to get rid of it.
Any ideas?

Don't want to freak you out but we had this when I was a child and ended up pulling the floor boards up and found a dead mouse. No idea why it smelt like cat wee but it did

Could be gas.
I had a similar smell in my kitchen and it turned out to be the cooker was leaking.

The gas check has just been done. The smell is stronger near the floor. The floor is tiled in the kitchen and laminate in the dining room. It's an L shaped room.

You haven't used that paint from b&q have you?

@gamerchick paint??

It might be that paint that was on Watchdog

I've been googling this as we sometimes get a smell of cat wee in the kitchen near the back door although I haven't smelt it in a while so still no idea what it is. But most of Google's answers were:
Dead animal in wall/under floor
Damp/rotting wood

I also thought it could be from the very overgrown weeds in our garden although not sure why it would smell inside

We had a cat wee smell in our car and in the kitchen. Turns out it was an unneutered Tom cat pissing against the back door. The smell came in through the gaps. Same with the car. He has pissed on the door and also the wheel arch which made the smell come in through the engine and door.

However it sounds like that's not the case for you. Dead mice can smell a bit like that under certain conditions. A dead rat though makes a huge area of a house inhabitable for a few days. I swear to Zeus I have never smelled anything as bad.
Have you checked shoes (trainers or footie boots to be exact)? There is an adhesive being used in some brands that give off a massive urine smell after they've been worn and got wet or sweated in.

Valspar paint can smell like wee.

Stop using bleach as it won’t work on cat pee, if that’s what it is. Just put a small bit of washing powder in the mop bucket. It neutralises the smell of urine. Cats spray vertically, so if a cat has got in, check the cupboard doors, walls, etc, then wash them. Have you been using the febreze that comes in a can. I kept thinking one of the cats had peed in the front room, so was using the spray. I kept spraying every day and the smell kept getting worse, before the penny dropped that I was using too much of it.

I think our feline visitor must have sprayed. I've given it all a good mop with white vinegar and cif floor cleaner. I've taken off the kick boards and they are ok.

It's driving me nuts as I still can't get rid of the smell.,I've had the kick boards off and can't locate anything which under there. I've now dissolved some nutradol powder in the mop bucket and mopped the floor and kick boards and up the cupboard fronts. I'm hoping it works!

The neutradol solution seems to have got rid of it, thank god.
Do cats spray if they are neutered? Or is it just a male cat thing?

It sounds like you’ve got to the bottom of it, but we had the same at the top of our cellar where the cats don’t go. Turns out that the glue in some shoes gives off a really strong ammonia smell when it gets wet and dries out.

Have you got any damp shoes knocking around?

Sounds like the cat has been spraying, they are devious and quick...

Yes male cats do spray if they're neutered as so female ones. Glad the smell has gone!
