Binky's blast-off into outer space (outside) to battle aliens (bugs) is delayed when he realizes he's left something behind - and it's not the anti-gravity kitty litter.
A loveable and delusional house cat named Binky, who, while in hot pursuit of an alien wanderer (a bug), falls out of the space station porthole (the bathroom window), and finds himself in outer space (outside the house).
Binky's become so comfortable in his role as an official certified space cat that he's battling alien invaders from the comfort of his own bed, but his complacency's shaken when a new kitty invades his turf.
