I tried time and time again to get one of my cats to walk on a leash [1], and it was a huge failure. Truthfully, no cat owner I know puts their cat on a leash. But you know what? The cat in this video — Boomer — is a pro on a leash, thanks to his animal-trainer human. Watch as they parade through a dog show and meet a whole bunch of dogs. Boomer takes it all in stride, playing with the pups and letting a few of them lick his head. It's almost cute enough to convince me to attempt leash-training my cat again. Keyword: almost.
