I hope I got this in the correct forums.
Anyway, this is what I am hearing. She is telling me she has "taken care of reptiles for years and worked with the Chicago Herpetological Society for even longer" and that she can "cite hundreds of sources saying all captive snakes must be fed an all-rat diet unless they are in a zoo or breeding program. If you don't, you must supplement them and provide UVB lighting."
I have never heard of any of this, except for the supplementing.
Greens snakes are fed insects and things is captivity. Asian vine snakes are fed house geckos. And there are others that are fed things that are not rats or even mice, so...
Just thought it would just be a interesting conversation.
