I don't think it is pregnancy related. I think there is something else going on with Ashley. That she squats right in front of you seems odd. I think another vet visit is in order.

I am pregnant with my first child. My cats have known nothing but me for years and years and years. My oldest is 13, I have 2 8 year olds....on down to a 1 year old kitten. They are not acting up...in fact, if anything, they seem attached to my belly.
