I had a large italian that would have been called a jumbo, she weighed about 360 grams I think and had a poor little 100and?gram english that would try to mount her, was like watching a bull ride at a rodeo, he eventually took to the other smaller brown jap.
The main point the others haven't bought up that I'd seen mentioned in the past numerous times on reptiles in relation to feeding snakes birds is that they produce alot sloppier and stinkier poos, so long as your prepared for that than go ahead.
I've also heard the argument against it a few times too, am on the fence on that one, some say it's fine to vary the diet, others say there's risk they'll favour the new food and not go back to their normal food.
We haven't varied the diet of ours except when she had mouth rot and we were stressing over her losing too much weight (she wasn't and the vet said her weight loss was in normal amounts and she could stand to lose a little anyway, but it was our first time with her catching anything, so we were stressing out and tried feeding her small stuff like chook hearts etc that would be easier to get down).
