Cage Info:
Cage Type - Picture given

Lighting - Zilla Daytime and Nighttime at 100 watts.
Temperature - Temperature is 70-85. 85 baskspot (because baskspot is so close to lamp) and 70 at bottom. 75 throughout the night. We have temp. gauge
Humidity - We mist twice, plus the ground is damp so the heat creates a dense humidity about 55-60 percent.

Location - Central California. Central Coast area.
Current Problem - I just got off of work, come home, and find that my chameleon has a huge gash coming out of his tail. He's been fairly unhealthy, we went to vet, treated him with antibiotics for an infection. Finally, he started shedding, and sheds every two weeks. He is in a current shed, then I find this gash underneath his tail! Any ideas on what it is? We'll be most likely taking him to a vet but not immediately. Is there anything I can cover it with to keep it from protruding? We start school tomorrow and my lady and myself are there all day! Plus we have to make an appointment. Picture of it below.

Did it go back in?

It could be a couple of things. If it went back, then it's not a crisis, if it's still out, you need to keep it moist and schedule a vet visit. I believe you can try soaking it in sugar water to see if that will help it draw back in.

They have a "vent" at the base of the tale that's sort of the universal opening to the outside for all body functions requiring access to the outside. So, the poop comes out there. Also, the penis comes out there (or, for a female, that's the opening to the vagina(? do they have a vagina?....it leads to the uterus regardless of what it's called).

Obviously, there's the potential for things to "pop out". If they pop back, it's not usually a problem.

**edited to add**

KY Jelly is the product normally recommended to keep such a thing moist pending a vet visit. Some have recommended (and made good cases for) olive oil. Hopefully you will have one of those easily available. If you do go to the store, the KY Jelly is usually found in the feminine hygiene aisle.

The protrusion hasn't. When he tenses it does, but it eventually comes out again. I was sort of hoping it was apart of the anus it isn't at all. This protrusion is on the tail itself. Like the skin got weak and split open and whatever that thing is came out a bit. But definately have to try the KY Jelly...just going to have to wait 'till tomorrow to get it. Everything is closed. That's what sucks about living in small towns!

WOAH that looks like it busted out the back of the pouch. Is it coming out of the cloaca or from back further?

A vet visit is in order.

Yeah, that doesn't look like a prolapse unless he has some funky anatomy. Get him to a vet ASAP.

wow! Let us know how you made out please at the Vet
