There aren’t all that many house cats running around with 6” or greater paws.
Mountain lions, either, for that matter.
I dunno about mtn lions. The one’s I’ve seen get pretty big. They can have good sized paws, and prints I’ve seen are close to that size.
Thing is that picture does not have a tail like an African Lion. It has a tail like a puma. And the animal is way to “fuzzy”....
