Who says animals don't have personalities?

I believe my cat has a shoe insole fetish. I have a pair of old work boots that, ever since I've brought her home, she's been into them, trying to get the insoles out. Now that she's almost full grown, she gets them out easily and now they're her favourite toy. She transports them around the house, attacks them, bats them around. For whatever reason, I came home today and she had both of the insoles pulled out of my Dr. Martin workboots too. She also has this weird thing of biting people when you play with her. She doesn't do it hard but after she bites, she licks where she bit.
