So I was listening to some exotic animal vets talk about reptile care and I learned some new things. I just wanted to know what you guys thought.

The first thing was food size. The vet said that food size should be around the diameter of a snake's head. I know this is true for chameleons and probably other lizards, but I've always read and fed my snake food that is the size of the fattest part of his body. If I fed the diameter of his head I'd probably have to go back to rat pinkies, it's a very big size difference. So I'm wondering, which is correct?

The second was UVB lighting. The vets agreed that nocturnal reptiles don't necessarily require UVB, but they said that studies have shown they definitely benefit from it. I've decided to hang a UVB bulb above my BP's cage. What do you guys think, just curious.
