Hello Thea!
I was in the same boat as you last October! Yes, they are addicting... I still can't bring myself to get within 5 feet of a full-grown burmese! So you are waaaayyy ahead of me now.
We have 2 ball pythons (like that 3rd picture) but they are still young - the youngest one is less than a year and is less than 2 feet long, the other is 2 years old and is over 3 feet long. Our latest addition is a hognose snake. It is amazing how much I've learned about snakes in the past 2 months. Especially with the hognose and the ball pythons - they are completely different characters it's amazing, e.g. balls are nocturnal, hoggies are diurnal, balls constrict their prey (very fast and very efficient and very intimidating) while the hoggie will kinda hunt but is scared of the food and would rather have a dead one because it takes him a long time to get that venom working into the food (very inefficient in my opinion). And even with the 2 ball pythons, they are very different too. The younger one is very easy going, always happy, and eats every time food is offered. The older one is a prissy one - a little thing not quite right with her house and she will refuse to eat - and she's moody - sometimes she's okay with just sitting with you on the couch, other times she'll hiss at you if you even come close.
My son loves to tell everyone that he has 2 constrictors and a venomous snake which almost always gets me a "talking-to" from my parents of how I'm putting my son in extreme mortal danger.If nothing else, I love having the snakes so I can show everyone there's no reason to fear ALL snakes.
WELCOME!
