When Craig Armstrong met his cat, Millie, at an adoption center in Utah, it was a match made in mountain climbing heaven.
"She climbed up my back and sat on my shoulders," Armstrong wrote in an article for BackCountry.com where he works. "It took about four seconds to realize we were now partners and would be going on many journeys together."
Millie accompanies Armstrong on his weekend camping adventures where they do a lot of hiking and rock climbing. From the looks of things, Millie doesn't have a problem keeping up.
"She literally loves to climb things … if there’s high-ground she’ll seek it out," Armstrong said in an interview with Bored Panda. "She’s an incredible athlete but steep juggy routes just aren’t her thing. When bouldering, though, she’s done some pretty amazing gaps and dynos."
Armstrong told the outlet that it took a lot of practice to get Millie to follow him and not be distracted and run off. He also prepared the cat for their excursions by taking her to local parks and exposing her to the outdoors.
This little feline adventurer even has her own set of gear, including a harness for safety. She is everything a good climbing partner should be, Armstrong says.
"She never complains, no matter how bad it gets," he wrote on BackCountry.com. "She always wants to go higher, and she pushes herself hard."
We're sure that having a furry companion to snuggle up with in the tent at night isn't bad either. Check out some of the pictures below of the thrill-seekin', rock climbin' kitty.
