Texas Indigos are very docile and intelligent animals, though a bit more difficult to acquire than their Floridian and Georgian cousins, but there are some out there!
You might wish to check the breeders list at
www.indigosnakes.com and contact a few on the list working with them.
As testament to their temperament, here’s a photo of my eight year old step-son with a male Texan that is just under the 9’ mark and growing.
You might also wish to look into the acquisition of one of the cribos as well, as they are all legal in FL and generally well mannered..
Best regards,
Jeff
