I'm a new bp owner (today actually) and everything I've read is that they don't need UV, so it's interesting the vet was surprised about the lack of UV lighting.
The bp's that people keep in racks with no lighting seem just fine.
They're nocturnal animals who are underground in the wild, so lack of UV shouldn't be an issue.
You know that & everyone on here does too, it's strange the vet flipped out...
