Yeah .... they can be easily fed on frozen thawed XL mice , rats , chicks or even Multies .. some people mix them all up to Lee things interesting...
Pretty sure recent studies show that Mice and Rats are virtually identical nutritionally-wise .
When the Royal gets to a decent size It's just easier to feed one rat rather than two , three or more XL Mice .
In my area frozen small rats are SIX times more expensive than XL mice - so feeding a rat is not really a saving much if anything .
Frozen thawed are much cheaper and more much convenient than feeding live ones ..
