In honor of National Cat Day (which is apparently a thing!) transportation startup Uber will deliver app users kittens. In exchange for $20 which will be donated to a local animal shelter, the service will show up with kittens you can snuggle with for 15 minutes. The company is running the promotion in New York, Seattle, and San Francisco from 11 a.m. to 4 p.m. -- so only our west coast friends still have time. However, they warn that "demand for kittens will be very high and availability very limited."
