I have cats, but they mostly pee where they’re supposed to.

The icky cat pee smell happens when they pee on things not designed for cat pee, and then those things aren’t adequately washed. E.g., suitcases, clothes, curtains, backpacks.

So, someone in my position might not think cat pee smells terrible, except I’ve been to houses where the cats weren’t as well-behaved, and those houses stank.

When my wife and I were house-hunting, one of the houses we disqualified solely for the cat pee smell.
