[Lisa and Pic]

Not sure what is happening with your little one, but for Piccolo.... When she starts doing something obsessive like that I have finally, finally figured out that she has some type of hair that has worked its way into her mouth and sometime down her throat. It is really tough to find, too. (The first time I had to take her to the vet because I could not figure out what was wrong.)

There could be a reason why she is doing this, maybe she has some type of pain in her mouth. Hope you get things figured out.
