Cat likes to wash vinyl
Winnie often licks the vinyl chair cushions repeatedly. Either she thinks they need cleaning or she really likes the taste.
I've also caught her washing the leather couch and today she scrubbed a stripe from a page of my day planner.
If she finds a photograph she'll wash that, too.
Normally I don't worry about it but the sound is annoying.
Why does she do this? Does she like the taste? The texture? Is there some kind of chemical smell she enjoys? Is there a chance she'll injest something harmful (developer chemicals, mold-release agents)?
