same here -- my foster pg kitty started shredding newspaper yesterday and today she has a watery discharge -- in fact, sounds just like what your kitty is going through (larger breasts, no obvious milk leaking). I have no idea if this is the beginning of labor, but I know it has to be soon!
it's exciting, isn't it?
It's also interesting that tonight is full moon, and when I worked at an answering service in college, there were always more pg women going into labor during full moon. Here's info on this month's full moon, from www.space.com:
April 13, 12:40 p.m. EDT: The Full Pink Moon. The grass pink or wild ground phlox is one of the earliest widespread flowers of the spring. Other names were the Full Sprouting Grass Moon, the Egg Moon, and -- among coastal tribes -- the Full Fish Moon, when the shad came upstream to spawn. This is also the Paschal Full Moon; the first full Moon of the spring season. The first Sunday following the Paschal Moon is Easter Sunday, which indeed will be observed three days later on Sunday, April 16.
Keep us posted!
