Not a cat's foot, but as mentioned it is mammalian. Here's a hint... think 4-legged, outdoors, and a wee bit higher.
I have to work now, but before I go, another hint.... It's not canine of feline. I'll check back in when I'm done.
Perhaps I picked one a little too far outside the box. Lol Bonus hint.... an old, very popular cartoon movie was made about one of these. From baby to adult.
