Selling excess feeders to pet stores?

[Bogertophis]

Can't quote you any prices as I stopped doing this some years ago & it also depends on your location, etc. But for some years I had a pretty good side business
selling rats, mice & hamsters to local stores, a museum & a few private individuals. Even though I had a house-full of snakes to feed, my rodent production was
way more than enough for my own needs. It helps to figure out what it costs you to produce them- it's likely to be more than a larger scale source they may be
using, so unfortunately you'll have to be competitive in your prices. (& they may or may not tell you the truth about what they're paying)

The other thing is that pet stores need reliable sources...you may not have enough to be their constant supplier but it wouldn't hurt to talk it over with the owner.
(Do they only want live, or can you also sell them frozen excess?) If you plan to do this as more of a business as I did, one thing that helped me is that I could
give them what other sources could not. Example: They had been selling hamsters sourced from a large supplier that paid NO attention to inbreeding, which resulted
in "c/b" but inbred hamsters that behaved as feral ones would have, biting viciously & virtually un-tameable; they lost money on them, because instead of selling
as pets, they had to reduce prices & sell them as snake food. They also lost the trust of some unhappy customers...no one wants a pet hamster that attacks their
children & bites hard! As a hobbyist, I produced healthy, tame AND attractive hamsters that they "sold like hotcakes", & in addition, since I had "customers"
that could consume any that didn't measure up, I even guaranteed free replacement (on my next weekly delivery) of any hamsters whose temperament was less
than perfect. They rarely took me up on that- they didn't need to- but it assured them they never lost money, & it cost me nothing while gaining good will & trust.
If you work with them, both you and locally-owned pet stores will come out ahead...good luck!
