Maybe try the dryloc paint or the epoxy covering for garage floors. That should seal the concrete better and maybe stop the odor.

I'll say the obvious question. Why did you buy a house with urine on the walls and smell like cat pee?
To help though, you can take down the drywall and replace it. For the concrete, can you add a small layer of new concrete? Iike a skim coat?

Always told my kids if the person they were dating loved cats they should dump them.
Cats are awesome.
The owners who let their cat pee all over in the room of that house are not awesome.

If it's in the concrete and you are positive its nothing else I'd get an angle grinder and take off the top thinnest layer of concrete. Use a buffing type that will leave the top smooth and not take big chunks or grooves out. Then re finish it afterwards with a sealer. Maybe even get urine be gone or other cleaner before you re seal.
What exactly are we talking here--poured concrete floor? Concrete block walls (like a basement bedroom)?
If you're talking concrete walls--either poured or block--that surface is likely quite porus. Could be that the sealer you used wasn't able to adequately bridge the gaps to fill those pores so odor down in the concrete is still getting out. Any shellac I've worked with has been pretty thin consistency, and IIRC is mostly alcohol that evaporates away (low solids) which would be inherently bad at bridging big pores.
If what used was truly a shellac (and you haven't painted over the top) subsequent coats should "melt in" without any issues. Perhaps go back with another wetter/thicker coat of the same stuff, or use something different that is inherently better at dealing with big pores.
You would probably want do some research, but I think most finishes can be applied over top of shellac so if you try something else you may not necessarily have to strip the old stuff off. Something like the oil-based version of Kilz might be worth a shot.
I don't see how grinding is going to gain you much... it sounds to me like the urine is soaked down into the concrete and your problem is that you didn't achieve a good seal to keep it from coming out.
