I currently have a 5 month old panther who has recently lost a foot to gangrene and another two are infected. Even though I have probably stopped its progression she is in a very bad state and is pure black in colour now (used to be red and white) and very unresponsive. I'm taking her again to the vet tomorrow but it would be great for a little input into the causes of gangrene in chameleons as there isn't much information about it. It's strange that it started in three feet at the same time.
