This is an interesting question.


Personally I don't think people loose interest in the animal per say but in the husbandry requirements.

For instance...I used to breed ferrets. I pry had 100 at the height of my breeding. They were registered, shown, sold, etc. I bred for color patterns, temperment, etc. But after a few years it became a job with no benefits.

Do I love ferrets? Absolutely
Would I bred again? Maybe
Would I get a huge collection? Never Again

I never lost interest in them but the joy I originally got from them was lost in the "job" of their care and upkeep. I think anytime you get above "pet" status (meaning more than 1 or 2) then it becomes work. Work can be fun and enjoyable (just like your job that pays the bills). But once it isn't fun or enjoyable for you it is time to move on (from your pay the bills job or a hobby that has grown too big)

Very few people have enough long term vision to know today that over the lifespan of a snake (25+ years) that their homelife, finances, time, etc. will allow them to devote the "work" necessary for the animals proper care. I would rather see them move on then allow the animals to waste away due to neglect.

Just my 2 cents.
