Interesting, I did not even know they don’t have thumbs. But a google search reveals that there is a mutation that gives them more toes , so therefore they definitely could if it gave them some advantage.
Like in the advert? Haha. I hope so, how funny! perhaps if it gives them an advantage in life then perhaps through evolutionary changes (and many years) then cats with thumb-like digits might be common place-how odd would that be? ha lol
I think opposable thumbs evolved in primates to help with gripping things, like when climbing a tree, for example. Most cats don’t climb trees as much as primates, so I’m not sure there is a good reason for a thumb. When cats climb trees they already use their claws.
So if there was a kind of tree-dwelling cat then maybe in a few million years it would develop something like a thumb to help grip branches.
