The Cracker snuck some bright aqua blue streamers into his bed and then peed on them.
He has white sheets.
So far I have tried: Biz. Spray 'n Wash. Clorox Bleach Pen...twice. Straight bleach.
Two of our three cats gacked up some of the same streamers. Luckily, I caught it right away and the carpet was saved.
I think I give up.
(Which will leave me with some time to try, again, to get more than a half dozen little purple spots of jelly bean drool out of the carpet without cutting.)
