Cat urine and concrete, Help!

I have an 8 year old male cat that loves to urinate on the floor around the litter boxes he shares with our other cats. He has been doing this since he was a kitten and has always lived with other cats.

We've tried everything to get him to stop. Haven't been able to keep separate litter boxes because he always finds a way to go in the other cats boxes even if the boxes are in different rooms. So now there are enough litter boxes for the three cats in the same area of our basement. We clean them everyday and use a litter deodorant. Although he has been better he still manages to leave a puddle on the concrete floor a couple times a week

We rent and although my landlord swears he doesn't mind I'm afraid the odor will only get worse over time. We have been using a water/bleach mix to take the odor out, not a huge fan of that method but my husband insists it's the only way to get rid of the odor in concrete.

Has anyone had any experience with territory marking cats like mine? Any advice would be appreciated.

My boy Molasses is a marker and the one thing I am sure of is Urine Gone Spray or White Vinegar not mixed with water, put it on straight from the bottle. I've found that Urine Gone takes stains out and white vinegar takes the order out, as well as stains. Good luck.

If it's just bare concrete, such as in a garage or basement, you might want to paint or at least seal it. That smell can be very hard to get out of concrete, which is, after all, porous.

2 cups hydrogen peroxide
2 teaspoons baking soda
2 drops liquid dish soap

Mix and pour on the spot and allow to dry naturally.

It will work!

Putting a sealer on the concrete is a great idea. The home improvement stores carry a clear water seal that will not change the color or texture.
Most are familar with the brand "Thompson's Water Seal".

I have used with good results www.weecleaner.com .
