Pregnant cat around 55-60 days along has had on and off for a few days a clear/pinkish balloon/bubble type thing that will come out of her lady parts. The bubble is small and if you rub her belly it comes out further. Not sure if this is the mucus plug getting ready to come out? or if it’s something else? She has also been having lots of poops. And will sometimes stand in the litter box pushing and nothing comes out. Kittens are moving lots. And mama purrs and seems happy as can be.
