Anyway, to finally get to my point, maybe Squeak gets over stimulated from the wiping motion. Does she only do it when you are moving your hand/arm? Does she do it when you pet her too much?

She does it when I'm wiping and just for NO reason. You know how she was when I was on the phone with you. She's like that most all the time.

Medusa- I usually take my finger and place it on her nose firmly and tell her, "We DON'T bite", or "We DON'T act like that". SHe will tuck her head back and squint her eyes. I think she knows she's not supposed to act that way, but sometimes she just does. Maybe it is over stimulation, as Jazzcat said. Maybe a squirt gun would work, but then again this is the same cat that sticks her head in the shower to see what Mom is doing in there.
