Meet Millie the cat. She’s unlike most cats. Millie is a mountain-climbing cat who shares the same passion as her human Craig Armstrong. "I met Millie, my climbing partner, at Furburbia. We went into a tiny room to have a chat together away from all the other noisy campers. She climbed up my back and sat on my shoulders. It took about four seconds to realize we were now partners and would be going on many journeys together," Craig said via Back Country.

Millie has become a legend in the climbing world. “She literally loves to climb things… if there’s high-ground she’ll seek it out,” said Armstrong via Bored Panda.

Millie and Craig are inseparable mountain-climbing partners. "I met Millie, my climbing partner, at Furburbia... She climbed up my back and sat on my shoulders. It took about four seconds to realize we were now partners and would be going on many journeys together."

“Generally she does best on slab by routes where she can scramble from ledge to ledge. She’s an incredible athlete but steep muggy routes just aren’t her thing. When bouldering, though, she’s done some pretty amazing gaps and dynos.”

“I go on a lot of weekend climbing adventures. I always figured when I have a pet friend, I’ll take her with me,” Craig said.

“Millie has all the qualities a good climbing partner should have. She never complains, no matter how bad it gets. She always wants to go higher, and she pushes herself hard. But she also knows when to stop.”

“Whether she’s following me or I’m following her I generally just stay close enough to rescue her from trouble. I love that little furball, so I stay close.”

“She doesn’t like wide-open spaces with no cover, so I’d take her to a big island in the Great Sale Lake, get out of the truck, and start hiking up a hill. Rather than be alone out in the open, she’d follow me”

After a long day of hiking and mountain climbing, time to relax :).
