My theory is this...
Most people start out small, as an interest or hobby, go into business, and have the best intentions.
Not all, I grant you - but I'm thinking of people I actually know, here.
And then, it grows. And grows. And if they're really good, knowledgeable or just plain lucky, grows some more.
At some point, without them realising, the balance tips from caring for each animal, to having a wall of merchandise - the sort of merchandise that does need the odd mouse chucking in, and a bit of a clean out now and then, but the sort of merchandise that doesn't wail if it isn't looked after properly, and doesn't appear sick until far too late...
And it can be too late for the business by then.
I see it in all sorts of industries, not just animals, and it's a case of 'not seeing the wood for the trees', or 'biting off more than you can chew', take you pick of metaphor.
It's just that it's sickening when it is animals, and I'm completely with Linds on this one - it's a life, and one that we humans have chosen to take responsibility for, whether by breeding it, or by taking it from the wild.
Some people just need to take more responsibility...
Just my two-pence!
