Binky the space cat  & Binky to the Rescue by Ashley Spires

This simple graphic novel for young readers is an absolute delight.

Binky is a space cat since he has never left the family "space station" he thinks anything outside the house is outer space.  So Binky has a mission: to blast off into outer space (outside), explore unknown places (the backyard) and battle aliens (bugs). Binky must undergo rigorous training so he can repel the alien attacks that threaten his humans. As he builds his spaceship, he must be extremely careful with his blueprints - the enemy is always watching.

But the enemy are bugs and they are everywhere, so Binky spends a lot of time chasing and eating the bugs to save his humans from life under alien control.

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 realizes that he's left something very important behind and it's not the zero-gravity kitty litter.

In the 2nd book Binky the space cat and Ted, his stuffed mouse, fall out of the window and find themselves adrift in outer space (the backyard), the cat has to rely on his training to combat the aliens (bees and spiders) and to get himself home again. Although the feline returns safely, his trusty cohort has been left behind and Binky must save his best friend as one never leaves a mouse behind!

These are so utterly delightful.  I love the cat elements while still making this kid friendly.  It's hysterical when Binky toots after eating too many bugs "aka aliens".  Can't wait to read more Binky adventures.
