Well, mooching about in Dalaran on the beta (hoping no Death Knights were using Unholy Blight Rank 2 and crashing the server), I visited Breanni for more fetch balls and found the following…

A pet grooming kit. I tried it out… poof a blue puff of smoke….

and a shiny, sparkling clean pet …

Blizzard certainly know how to keep this pet collector amused
They really do seem to know how we tick. Shiny sparkles!
My lil Lurky now sparkles too.
I’m at 29 pets and counting… where am I gonna get the other 21 to get my Stinker?
