My funny kitty loves to rub her head up against absolutely everything - the carpet, my shoes, her toys, anything at all that's on the floor, the corners of drawers and cupboards...and even her food!!! She would rather rub her against her toys than play with them and when I give her a kitty treat, she'd prefer to rub against it rather than eat it! Is this just a quirk? She doesn't have fleas. She's been with me only since mid-August so maybe she's still marking everything with her scent?
