Go and pee on the area yourself. Your scent will mask the scent of the cat and you will let everyone else know the house is yours.
As others have said, the concrete is porous, and the urine has likely well-diffused into and through the concrete if the cat was allowed to do this for a long time. Also, higher humidity tends to "activate" the diffused urine. You can google for more details on that. There are enzyme solutions for treating concrete, different ones for cat and dog. I would research those. And be aware, it can take weeks and months to treat a urine problem in a concrete floor, because the enzymes have to diffuse down to where the urine is.
Skim coats of concrete aren't going to help, because they will be porous, and the odor will diffuse right through them. However, as mentioned above, there are epoxy based floor sealants and coatings that might help. However, the proper prep will need to be done, as they may not adhere to spots where the urine is bad.
The previous owner of my house let her dog use the garage floor as a bathroom. We did enzyme treatment, had a floor wash done with some kind of nasty substance, and put down an epoxy based finish (2-parts I think). For the most part, that has solved the problem.

If it's poured concrete, I would use muriatic acid (hydrochloric acid). It will not only dissolve/strip away the affected layers of concrete, but it will denature the compounds (or solubilize them) creating the smell. Excess can be neutralized by baking soda (if you don't dilute it much, you will need a lot of baking soda).
I helped a friend flip a house last year with a similar issue - he had good luck by tearing out the drywall, spraying with vinegar and/or bleach, and then using kilz on the floor and framing.
I look forward to his next post titled "Hydrochloric acid burns".
Anti-icky Poo &/or Lemon scented Lysol at full strength (not together). On horizontal surfaces you can cover with plastic to keep it damp since it will take time to work. Vertical surfaces may take some ingenuity. This can work on non-porous surfaces. MMV on concrete.
For what it's worth I had good success with this product:
Venus Laboratories Earth Friendly (Petastic) Pet Stain & Odor Remover
I was using it on carpet, not concrete though.

We were lucky that there was no evidence of the drywall being affected. She was a great cat but damn that was frustrating.
