What is a good product for cat urine odours. I am helping to clean out a house and need a way to get rid of the cat smell for the next tenant. There are no carpets just lino not sure where the cats have soiled so will probably have to open all the windows and give it a good clean..would like to eliminate the odours not just mask them.

Thanks

You may need to take up the lino and treat whatever flooring is underneath... if any urine has leaked under the lino and gone into wood or other porous flooring then that will be holding the smell. Just as bad would be a non-porous subfloor (eg tiles, concrete) which might reveal a sticky residue where urine has leaked through or behind the lino and can't soak into anything.

Depending on the severity of the stink - spayed/neutered cats urinating inappropriately? A few occasions or weeks or months? Entire tom cats? - you might be able to clean the floor base under the lino, but you might need to sand and revarnish or paint soaked floorboards or other porous surfaces, to banish a very stinky long term habit. Cat pee does linger.

If it's not a giant issue then scrubbing the sub-flooring with biological washing powder might do the trick, plus replacing the lino. (When the lino is up you will probably see the main areas of staining and can treat accordingly).

Otherwise it will need some kind of re-sealing and new lino.

The floor underneath is concrete..a couple of the rooms have had the lino replaced I think the rooms where it is worse is the living room and kitchen and they definitely need new lino anyway..

Fair enough - Up the lino, good scrub with whatever you can find... if the smell persists think of re-sealing the concrete, and you'll be good to go :)

You could try bioligical washing powder. We board cats and sometimes they do miss the trays and thats what we wash the pens down with. May need a few soaks though

This stuff is awsome and leaves a pleasant almondy smell.  I use it when my cat can't get it in the tray, it completely eliminates the smell.

Yep I use Simple Solution all the time, in fact every time I clean our litter trays.
