I have a male veiled chameleon who's about 5 months old and is beginning to be very aggressive. I'm not interested in handling him for fun because i don't want to cause any unecessary stress, but i will need to take him to the vet occasionally, clean his cage, and other things. anybody have any advise for handling an aggressive adolescent chameleon? Good ways to get them to warm up to you? any help would be appreciated
