BEHOLD! Space Cats!
I remember seeing Sylvester the Cat in "Space Jam", but I don't remember this...and did I just date myself with a "Space Jam" reference? Video's of animals are funny, video's of animals weightless in a space atmosphere is even funnier.
If your a fan of cats or any household pet, check out the video of an old school space experiment involving cats, and just for legalities...
"No animals were harmed while making this video."
