When could you feed alfalfa to rabbits?
during certain life stages (growth/lactation/pregnancy)
Consequence of feeding alfalfa to adult rabbits?
severe crystalluria
Can chinchillas have produce?

Can you overfeed [dark] leafy greens?
not really (can examine on an individual basis but still not really)
thumb = amount of vegetables

brachydont
What kind of incisors do omnivore SMAMs have?
elodont

- cheek pouch
- ridge within the stomach to separate food storage and foregut fermentation
Do omnivore SMAMs have a cecum?
