Tardar Sauce's Arizona-based owners launched a Tardar Sauce Tumblr page updated daily with pictures of their grumpy cat that went viral a few months ago. Since, the cat's been the subject of countless memes, ridiculous television interviews, side-by-sides with Parks and Recreation's Ron Swanson.

This weekend, the cat (and her owners) are on a mission to raise money for Maricopa County Animal Care and Control and will be all up for pets and scowls at The Great Southwest Scooter Fiesta in Gilbert.

The Southwest Scooter Fiesta is an annual event hosted by the Scooter Club of Metro Phoenix that includes a huge showcase of vintage Vespas and collector scooters from around the world.

The family-friendly event will take over Joe's Farm Grill in Gilbert this Saturday from 10 a.m. to 2 p.m.. Vendors include Vespa Chandler and 2nd Avenue Scooters as well as plenty of BBQ goods, raffle prizes, scooter awards, and pets up for adoption from the Maricopa County Animal Care and Controls.

Tardar Sauce was not available for comment, but we're sure he's thrilled to make an appearance and provide even more photo moments.
