Al Gore gets all the credit for inventing the internet, but it was cats who made the internet the unstoppable juggernaut that it is today. There isn't a video-sharing site online that isn't blessed with clips of cats misjudging the distance of their jumps, cruising around on their Roombas and terrorizing much larger dogs — the art form is the lifeblood of the internet. For the second annual Cat Clips screening, a curated selection of user-submitted precious cat footage will be screened live from 6 to 8:30 p.m. Tuesday, April 2, at Urban Chestnut's Grove Brewery & Bierhall (4465 Manchester Avenue; ww.stlcats.org). Snacks are free and there will be a photobooth, raffle baskets and cash prizes for the top two clips. Tickets are $20 to $40, and the money benefits Animal House Cat Rescue.
