My cat has a shoe fetish!

I have a 12 year old spayed female cat that I have belonged to since she was a kitten (yes I said I belong to her.. any cat lover understands that phrase.) Anyway.. when I take off my shoes (stinkyfeet shoes too ) she rubs herself all over them, plays with them, and attacks them, rubs her face in them, then she wraps herself around them and lays there like she's protecting a lover. She loves all shoes including my kids' and husbands... boots, flip flops, sandals, old, new it doesn't matter, if it's a shoe, it's HERS She's a FREAK!
