No, I smelled it before, I think he may have urinated there earlier today (the comforter was SOAKED with it). He's due for his annual vet visit in the next month or so, this will definitely be brought up. I just hate feeling like I don't know what's going on with my little guy. Flur, it's hilarious, my cat looks just like yours. Except with a much less serious look on his face. (Vlad is the little jester in our house.)
