Most pet cats will become timid or defensive when outdoors, but not Millie – after being adopted by her mountain-climbing owner Craig Armstrong, Millie has become a feline hiking and mountain-climbing legend.






“She literally loves to climb things… if there’s high-ground she’ll seek it out,” Armstrong said in an interview. He had nothing but praise for the tenacious little athlete: “Generally she does best on slabby routes where she can scramble from ledge to ledge. 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.”
