Hi, we really need some help! My cat starts to have a big belly, but it isn't round, it feels like she has a huge lamp on one side of her belly, and a little smaller on another side. some of her nipple are pink and big, some are really small and normal color. one of her nipple has like a big sac filled with some kind of fluid and very red. It's not painful, because she lets me touch it. she became very passionate lately, wants me to pat her belly. I don't feel any kitten movements at all. she has very good appetite, sleeps a lot. lately her belly is so big she can't clean herself. Unfortunately I can't take her to a vet now.
