A week ago I found my cat Karl's piss in a laundry basket in my room. This is ridiculous behaviour for my 10 year old SPCA rescue cat of a number of years. Fast forward a week. Ten minutes ago. I have a bad cold. I get home and realize my door is open, having left it shut since Karl's mishap. I check the place the laundry basket last stood and I feel nothing. Dry clean clothing, different than those drenched a week ago, so rank. Then out of nowhere a damp spot! Very small. Nothing of notice. Smell, none. Discolouration, none. Taste, cat piss.
