I was thinking the same way back in 05 when we expanded into ball pythons, and worried the bottom would drop out soon. The thing I have seen is that while some are dropping out others are getting in. As the prices go down more will be sold as "pets".
Basically the way I see it is, it's not a get rich quick thing as some thought back then. If you love the animals and don't get over your head as far as caring for them you will be fine. (I've seen lots of people that can't afford to feed them in these harder times) And as time goes on, and we get olde,r there will be more "kids" asking for a pet reptile. I figure there is lots of customers out there, as long as they have good luck, good success, they will stay in the hobby.
