I agree: that's a lot of fur! Cats should poop out the fur but those are some big clumps. The best thing for that is brushing.Looks like a lot more poop than there was in your first post, so hopefully its improving. Is that light-coloured stuff hair/fur? I'm not a vet, but it looks like a lot of hair to me... Maybe that's what was doing it? How is she?
I don't know where you live, B Bbydoll , but I live in Maine and one of our cats has been shedding a fair bit this week and even barfing up a little fur -- we wonder if our strange weather (50 degrees one day, 5 the next!) has been causing it.
