I am wondering whether a royal python would be able to get its nutritional needs from non-mammalian food sources. I ask this for two reasons. The first simply being that I would not like to feed mice, but the other reason comes from the fact that when young, they (the snakes) must eat things that are smaller, like some sorts of bugs. In replicating a natural environment, it would interest me in also replicating a more naturally diverse and progressive diet (aside from the total lack of mice, of course). Back onto the first reason, however, if this is not a good idea, I may look into an eastern hognose snake instead, because I would not mind feeding amphibians so much.
