Identity Crisis

I'm sitting here giggling uncontrollably right now because my dog is attempting to play with two of the cats. The cats are climbing all over their jungle gym - then jumping down and running around the perimeter - then scampering up to the dog with their tails fluffed up - until the dog responds. Then the two cats run away as fast as they can and climb to the top of the jungle gym and stare down at the dog.

I can tell my Greyhound really wants to play - but doesn't understand how to climb on the little platforms like the cats. Too cute.
