First, how much cuttlebone is ideal for a 1.5-2 inch RES? Is there such thing as "too much"? Advice on size relative to everyday objects would help :]
Second is out of curiosity: why are carrots on the "moderate" list of vegetables instead of being a staple? How often can I give carrots, and is it harmful if I feed them too often? At least once or twice a week I give my RES some shredded carrot (along with pellets and lettuce, of course. It is not the only thing I feed that day but it's good for vitA, especially for my RES who is recovering from an RI).
Thanks in advance!
