My female EB is due in about 3 days or so and for the last week she has been peeing in her whelping box. She then licks it up. She has free reign to go in and out as she pleases, for right now, but at night she will pee in her box and walk out of it and poop on the paper. I have noticed during the day she will be sleeping and sit up and pee then lap it up, then lay back down after she moves her blankets. Could this be because she is pregnant and doesn't know she's doing it for the pressure on her bladder, or just stobborness? Any suggestions how to stop it?
