How to stop cat peeing in kitchen corner?

[SoonToBeThreee]

Currently having work done on the house which involved removing downstairs toilet and extending the kitchen. At the time the toilet was removed, one of my cats started peeing where it used to be.
The area has been fully bleached and cleaned and new concrete has been put on the area to level it so I assumed all traces of pee would have been removed and she would stop.
I have a cat flap and she has no issue going outside to do her business.
I think the reason behind her peeing inside is due to the fact with all the work being done, she doesn't have a set place at the moment (used to have her own room with bed/food/water, but now it's wherever their stuff isn't in the way), also, when work is being done, often a dog will be in the house and the cats locked outside for a few hours during the day. I'm thinking it's a territorial thing, once all work is finished they will have their room back and whole house will be cleaned so no smell of dog.
Cat hasn't peed in a few weeks until we forgot to unlock the cat flap yesterday after dog had left so they were stuck in all evening and over night, she was let into the kitchen for her breakfast and went straight over to her corner.
How I can I remove the smell once and for all to stop this as the floor is being laid soon and don't want it ruined! Also, any tips on managing it while work is being finished? I'm due to have a baby in 3 weeks so really want to get this sorted out!
Sorry for long post, didn't want to drip feed.

As you say - she is looking for an appropriate place now her tray has been moved from one place to another.

Are you able to put her tray in that corner for the duration of the work you are having done so that she can find it easily? Cats can get quite distressed by changes to their environment. She may have chosen this spot because there has been a toilet there. She will be able to smell tiny trace of urea which we humans would be unaware of. It may be either attracting her to a "toilet" spot, or she may be trying to mask it.

Re: the smell she leaves - you could try "Simple Solution Stain and Odour Remover" - it's probably available in the shops, but you can certainly get it from Amazon. I found it helpful (though not totally effective - but to be fair I had four elderly incontinent animals in the house at the same time - a single cat should easier to manage).

I hope this helps.

Thanks for the reply, she doesn't have a tray, has a catflap to get outside and other than last night, always has access and has no issues.
The flooring is being put down in a couple of days so no time to order online, would bleach be enough to completely cover the smell?? I used that last time and thought I'd solved the issue but cats have better sense of smell than us! Could she just be remembering she's been there before?

Bleach wont mask the smell I don't think, you need an enzymatic cleaner as suggested, if you can't get any in time I'd was with warm water and biological washing powder and then use neat vodka when it's dry. I'd strongly recommend an indoor tray in the spot until she feels more secure again though.

Ahh I'll see what I can find in the cupboards/supermarket :) putting a tray there won't encourage her then? Don't want to make it a permanent thing...

Put a litter tray down for now. Maybe when all the work is finished you may be able to manage without one, but it's always best practice to have one regardless for when it's raining, or the ground is hard, or your cat feels unwell etc etc.

Put food on the corner where she goes,that worked well for me.

I don't usually allow the cats in the kitchen, they have their own room at night (with the cat flap in) and only occasionally go in there to wait while their food is prepared, or if the door is accidentally left open (which is a lot while the work is being done). I might try feeding her there to try and put her off as don't like the idea of always having the litter tray there.
Thanks for all advice though!

Apparently, cats like the smell of bleach- because they are furry weirdos.

Wilkinsons do a really good Pet Urine cleaner, which destrorys the smell. The spray the area with surgical spirit, which completely destroys the enzymes.

Neat vodka? ??

Oh no, I must have encouraged her with the bleach! 😂 thanks, I'll have a look in wilko, thanks everyone for the advice, hopefully will get her to stop this for good!

A little pervert friend who used to visit me got totally horny over bleach, even though he'd had the chop. He'd cry until I let him in if I was cleaning with it and then throw himself near it in a frenzy. I always had to make sure it was well and truly cleaned off. Then he used to hump what he could find that was soft - towels, jumpers even if I was wearing them, the throw on my sofa ...

However, he also used to put his nose in my coffee and whisky and inhale deeply, which is why the vodka confused me.

One of my furry murderers does that, too!

I wonder why?

I was using Milton sterilising fluid on the floor the other day and Omar started LICKING the sole of my shoes. The freak.

And obviously I need another expensive vet trip...
