My 5 month old doe's nipple was bleeding a little bit on the tip the other day and today I looked and the other nipples all have a red spot at the tip of them. Even the top nipple at the top of her chest has a red spot on it. I feel like the glands around the nipple feel swollen almost like when a doe has milk. She's not pregnant. I wonder what would cause this. She has been living in the guest room with a litter box on a carpeted floor for the last week so her conditions are really clean. I hope this isn't the start of some kind of infection.
