Remind me of this

Someplace in my house, a cat has peed. Not in the litter box. I cannot find where. I have spent hours on my hands and knees sniffing every inch of carpet and upholstery. I cannot find the source(s). Remind me of this when I start talking about getting a cute little kitten someday.

I don't have a happy thought right now. There is nothing happy about a house that smells like cat pee.
