This is Jimmy – he’s a polydactyl cat.
Strictly speaking this means he has more than the usual number of toes on his paws. And that is true.
But, what it really means is that because Jimmy is also really clever, he can actually use them to give a ‘thumbs up’ when asked.
Although I have seen pictures of other cats with this, he is the only one who qualifies as a thumbs up cat.
Jimmy is clearly very cool!
