Question: Are 3 "fingers" normal?

[shamenspace]

Took a closer look at my axie's lil toes and on his front left leg he has 3 toes(in pic) and on the right he has 4, is it normal or concerning or a genetic thing? He's never gotten hurt so nothing ever needed to grow back, just wondering

It's not exactly normal, but it's not a bad variation to have.
