As seen on Etsy:

Is your pet feeling left in the dirt because of his/her unsightly rear? I’ve got them covered... Rear Gear is handmade in Portland, OR and offers a cheerful solution to be-rid your favorite pet’s un-manicured back side.

Rear Gear comes in many designs including a disco ball, air freshener, heart, flower, biohazard, smiley face, number one ribbon, cupcake, sheriff's badge, dice, and you can even make yours custom, so there’s a Rear Gear for everyone.

I know this is a gag gift... and yet? There was a long blade of grass hanging out of my cat's anus yesterday. So, yeah. Maybe.
