Squirrel strikes up friendship with cat through window

ST. LOUIS, June 28 (UPI) -- A Missouri pet owner filmed their cat's unlikely friendship with a squirrel that became enamored with the feline through the safety of a glass door.

The video, posted to YouTube by Liza Reid, shows the squirrel and cat eying each other up and down through the sliding glass door at a St. Louis home.

The squirrel tries in vain to find a way through the door to reach the cat.

The smaller animal climbs all the way to the top of the window screen, but is unable to find a route inside.

"This squirrel is dying to get inside to play with the cat. He's determined to figure out a way in, even if it means climbing up the screen door!" Reid wrote online.
