Vent Drinking (Cloaca) Myth….Busted. Again!

Our good friend Dr Jonathon Howard busts the myth regarding Bearded Dragons (Pogona vitticeps) drinking via the cloaca (vent area).

Many of you may know, I myself published an article a number of years ago regarding this myth, too great acceptance. A version, albeit shorter, can be found online, here.

It has since been used in related Vet classes, talks, exhibitions, etc.

Why this myth is even still doing the rounds, I have no idea.

I found papers from way back in the 1980’s where Dr Wade Sherbrooke bust the myth. And also busted again by Dr Shane Simpson (The Reptile Doctor) a couple of years ago. Yet still it exists. Absolute madness.

Anyway, here is the video, plus some extra related studies for you to delve into.

So now, please shut-up about butt drinking 😉
