A pair of Jungles were my 2nd & 3rd snake, after having a docile Coastal for 2yrs. They don't grow very big, they are actually the smallest of the carpet pythons averaging an adult size of about 1.6 metres.
My smallest female is a dream, she is placid and friendly, not much bothers her.
The male was a little nervous when we first got him, and a couple of bites but nothing serious, now he's an angel.
My 4th snake was in fact another female Jungle, but she was a different story, she was extremely high strung, she'd swing her head around with her mouth open trying to bite me as I was holding her. I used to wear thin leather gloves, to prevent myself from pulling away and thus damaging her, and I just kept at it, now I use no gloves and she very rarely bites, and when she does she usually has a good reason too.
I've never had any of them bite and hold on, they have only done the strike and release bite.
They make great pets if you can get them young and handle them up while they're only little. Little Snake = Little Teeth!
Just remember every snake is different just like us.
This pic I think I've posted before, but it just proves how good Jungles are, my step daughter is 6yrs old, and my husband and I are quite comfortably with her handling the Jungles.
