I talk to my snakes in french mostly, being that most of them were born in Quebec I consider them Quebecois.
The ones from the West I talk in English to.
(I remember things better if I say them out loud, so it is an instrumentive game. Helps me remember sheds, feeding schedules, etc.)
Either way all they hear is a whole bunch of nonsense and illiterate jabbering.
I reserve my baby voice for the rats, they are strategically placed so that I have to chat with them on the way out the door, unlike the snakes they actually respond, come up, flash their bellies, do the slide and side shimmy, and reach out for a rub and/or finger grab.
Rotters are just looking for treats!!!
