Polydactyl cat seven toes/claws

This is Piper the seven-toed polydactyl cat. She's about 12 to 13 years old and doesn't like to have her feet bothered she's a feisty kind of cat it's her way or no way LOL.. I'm hoping one day to be able to get her doing her meow where she says hello and I mean you can tell it so good that she's saying hello. She'll let out three or four meows every time getting higher until it comes out hello! It's really really really strange but cool.
