There ain’t no meowntain high enough for this big cat. Yuliya Minina, from Stary Oskol, Russia, claims her three-year-old Maine Coon cat Kefir is “the largest cat in the world.” She regularly posts content on her Instagram as well as Kefir’s personal TikTok page showcasing his unfurgettable size, the Sun reported.

In one Instagram video posted on Minina’s page last month with over 2,000 likes, Kefir stands on his two hind paws and manages to open a door handle to make his way into the family’s yard.  He later sprawls himself out in the grass like a gargantuan cat-erpillar before taking over half of a reclining chair and climbing a tree.
