Ok-- lesson one on Ball Pythons
Ball Pythons are about the most docile snake you can have as an "animal companion" (heh heh, that's what PetCo calls pets)
They are almost never aggressive. The females may reach 6 feet maximum (Isis was 5 1/2) and the males about 5 feet. This is stretched-out length and really isn't that long when you consider that some boas and pythons can easily reach 10 to 15 feet or more.
They are also usually less active than boas. You only have to feed them once every week or so, (sometimes less in the winter or when they are shedding).
They don't wake you up in the middle of the night to go outside. They don't chew on your slippers. They don't cost a lot to feed. You can take them anywhere wrapped around your neck.. hehehehe. (And sometimes people don't even notice-- I used to take Isis with me often and most people didn't even realize I had a snake around my neck unless she started moving.)
They make incredible pets and you are much more likely to get bitten by a pet dog or cat than a snake.
So... not afraid any more?
