Not sure if this is actually a nutrition query, but now that windows and doors are open more (it's summer
) flies are getting in the house. And indoor-only Ruby not only spots them, she catches and then eats them. I find it rather gross, and I do try to encourage the flies to leave the house before the Rubinator gets them, but she's clearly a hunter at heart. So my question is, is there any harm in her eating flies, ants, etc. ?
