Snakes are addictive, it's hard to have just one.
My snakes are pets I plan to breed someday. I love them all, but I do have my favorites. All of my snakes have names too, I have it in my head that once I stop naming them they stop being pets.
I don't breed my own feeders because mine will eat f/t and I hate rodents.
As J.Coils stated it doesn't take much time to clean. I find it's pretty easy because I keep mine in tubs so it's just the tub and the water bowel that really need cleaning. If I was maintaining a lot of cages with decorations I would probably have less snakes.
