WATCH: Cat gives Chihuahua 'bath' and it's adorable

BLOOMINGDALE, Fla. - Gizmo is a 10-year-old Chihuahua but don't tell "Millie" that.

The four-month-old kitten and the pup have formed an unusual and beautiful friendship.

Video posted on Facebook shows the kitten taking quite a liking to the pup, thoroughly grooming him around his ears, face and neck. For a while.

The Chihuahua seems content until Millie gets a little too close, but after a warning or two, Millie continues on. "Gizmo is not so sure he wanted a bath from our kitty Milly, but he accepted," said their owner, Cindy Mertens. "They play together all the time, they are the best of friends," said Mertens.  

That's adorable.
