BOULDER, CO (CNN) -- Sometimes you just have to see something to believe it. That's the case for a circus of sorts, performing this weekend in Boulder, Colorado.
If there's one woman who can own up to the term "cat lady", its Samantha Martin. She said, "It started out very simply with a couple of ladders and a big rope I got from the hardware store...and a half of the cats are mine, I count kitten as half a cat. They are all my cats."
In rescues, strays, and misfits, Martin saw potential for something more. She wanted to show people you could actually train a cat. She quit her job as a zookeeper and ran away with the cat circus full-time; the amazing Acro-Cats were born. She said, "The cats roll barrels, push shopping carts, jump through hoops, do long jumps, high jumps, ring bells (and even play in an all cat band called the rock cats. Skateboarding cats, yes, bell ringing cats so you can train a cat to do just about anything."
The antics are silly, but they're helping a serious problem. Martin said, "Since 2009 I've found homes for 142 cats and kittens on this little guy hopes to be 143."
Each show a chance for a foster cat to find a home, that is if Martin doesn't adopt them first. She said, "I have enough space in my life, my heart, and my bus to take a few here and there."
Home is often a giant traveling cat-bus full of felines that are more than a funny show or a full-time job; they're family.
The troupe will be in Boulder through the weekend, then they head to Denver, followed by Colorado Springs.
