I have a 3 year old Grand Cayman hybrid from David Blair. Who have never tried to bite until yesterday when he actually bit me on my arm. I had him since he was a baby. The worse for him was only tail whipping while he is in his cage. I always thought it was territorial thing. Once he is out of his cage he is as calm as a bearded. I usually take him to the bath tub once a day so he can go poo poo. When the weather got warmer last month I started to let him stay out in the patio for about 2-3 hours a day so he can get some natural sun light. After about a month or so he became very aggressive. Now he even open his mouth as me as I walk by the cage. I don’t think it’s the temperature because his basking area is 115 plus. Have anyone had the same experience? Or is he becoming aggressive because of the age? His birthday is 10-15-08.
