I believe I had 8 ball pythons when I got eggs my first season (2008-2009). I have acquired more snakes since then (both purchases and hold backs from clutches) and have no intention on stopping. I have 13 ball pythons now (plus other snakes) and have plans to add many, many more. I have permission from the husband that as long as we can support them (financially and physically keeping up with them) that I can have as many as I want. He even offered that once we buy a house, I can build my own facility so I can expand if I want.This hobby is always changing. New colors, new patterns, new possibilities. It would be extremely hard to stop where you are. There will always be something new that you want. My next purchases will be new enclosures followed by a het pied normal female. Then I have a nice long list of future snakes to buy (plus more racks of course).
No, its not odd to buy morphs just for pets. (Many people buy show quality purebred dogs for just pets with no intention of showing or breeding) Its just that most who get into keeping morphs like to breed them. My snakes will always be pets first, breeders second.
