I have a doe, 3 years old, about 20 days bred (I hope) who had a negative fecal done yesterday, but her gums are off color. Her eyes are fine, but her tongue and gums are not as pink as they should be. I check them weekly so this is a new thing. She is totally healthy otherwise, eats fine, 170 lbs. What would cause the off color if it was not a parasite? The vet did the fecal by the way, still haven't located a microscope :/.
