Well, I saw a tinge of blood on Pennie's anus tonight. Do cats bleed while in heat? Or is this something to be concerned about? Her poops are orange-ish and soft, not diarrhea. Her kittens are almost 8 weeks old and some of them (maybe just one, I don't know) are pooping white, runny, foam. WHAT IS THIS?! I'll be calling the vet on Monday, but need to know if I should buy some OTC wormer tomorrow. Does this sound like worms? Thank you, in advance, for sharing your wisdom!!
