I've heard of many large reptiles hitting a certain age and suddenly turning on their caretakers, even if they were tamed as juveniles... There are instances of savs, black throats, etc turning aggressive almost mechanically after "puberty". My grandpa even had a caiman back in 1948 when there was no regulation in the pet trade... He got it dog tame, then when it hit 3 feet it almost immediately started attacking him and he had to surrender it to a croc farm. A lot of people say that tegus do almost the opposite, starting out aggressive then turning very tame very fast at around a year old. What do you guys make of this? Do you see this in your tegus?
