When Harold Ramis passed away on Monday, the world felt a blow at the loss of one of the best comic talents of our generation. To pay tribute to his genius (and also probably to give themselves an excuse to dress the hell out of some kittens), The Pet Collective has created this adorable remake of the film starring kittens as the main characters. (True fact: Kittens make everything better.) (True fact #2: Watching this video on mute while listening to the Ghostbusters theme is likely to make you want to cry. Keep an onion handy as an excuse.)
