I agree with Sam, it's a shame they are so cheap as some people see them as disposable items....I bought a ferret finder off here a couple of years ago, his reason for selling it.....I can get a ferret for a fiver, if it doesn't come out I'll just get another one. One of my ferrets disappeared into a bank last season and was too deep for the locator to pick him, I just sat it out well into darkness until he came out. I wouldn't leave a ferret anywhere any more than I would leave my dog! and if one turned out to be a crap worker I'd just keep it as a pet and get another worker.
