Binky is a space cat - at least in his own mind. He's really a house cat who has never left the family 'space station.' Unlike other house cats, Binky has a mission: to blast off into outer space (outside), explore unknown places (the backyard) and battle aliens (bugs). Soon Binky is ready to voyage into outer space. His humans go out there every day and he's sure they need a certified space cat to protect them. But just as he's about to blast off with his co-pilot, Ted (stuffed mousie), Binky realises that he's left something very important behind... and it's not the zero-gravity kitty litter.
