My father in law has a veiled that has stopped eating the last week or so and this morning there is a red thing hanging out the backside. We ordered some zilla caloric supplement stuff. Not sure what is going on and need help.
Please post some pictures of the chameleon and a photo of what's hanging out. Could be a porlapse. Then please fill out this form so that we can better help you. https://www.chameleonforums.com/how-ask-help-66/
If it's a prolapse, it needs to be kept moist with K-Y jelly until you can get the prolapse back into the chameleon. If you don't do this the tissue will become neurotic and that is not good.
