You're so kind to share your wonderful fur discovered with us too!
Don't ever let anyone ever pressure you into setting a certain 'price' for your cats, being against an open bid, a raffle, anything your heart desires. A lot of people in this community forget that this is 100% a free market and you're entitled to do whatever you want with your kitties, whether selling them at a price that not everyone will agree with - there's no 'set' price standards, only suggestions made by community members and it's ultimately up to you to choose. As long as you're happy with the price/method of selling the kitty, that's all that matters.
People will always try to point the finger and blame someone for "crashing" the market but ultimately selling the initial kitty with the new fur/trait means that buyer is more than often a future competitor and will enhance the supply of that fur/trait in the market and prices will go down, this is natural and nothing will stop this. What happens after you sell that kitty? That buyer and you will continue to breed out that fur to sell, and those winning bidders of your fur will also more often than not sell ASAP (people trying to quickly make their money back as soon as they get an offspring with the fur in question), and they'll try to sell the duds, etcetera. Someone will always be unhappy and you can't satisfy everyone's discerning eye so you might as well set your kitties for the prices you think are reasonable, and don't -ever- let anyone bring you down.
There's also nothing wrong with sending duds to the menagerie. Sometimes the duds are what can bring down the prices of the actual fur even faster as duds aren't really that difficult to breed out and are so much more discounted than the actual fur initially, I know I'd buy a dud over the actual fur as a result. Nothing wrong with sending duds to the menagerie at all to clear space as well!
TL;DR: Don't worry about upsetting anyone! This is a free market and you are entitled to determine prices and the means of selling kitties as you wish, be happy with your choice for you can never satisfy the entire community.
