I think gaboons are the most beautiful animals on the planet. I love ALL hots, and I do not think badly of people who keep them, but I think there is definitely a line between a pet and not a pet. I do not believe that a venomous snake in my care would be as happy as it would be in the wild.
In other words, no. Even if I were experienced enough to feel comfortable working with hots, I do not personally believe that they can be kept happily in captivity.
