Please stop this practice, if you are thinking of using this practice, please do not do so. It's not clever it is obnoxious. I mean this even when I have literally no interest in the animal posted, what makes things worse is then the breeder also seems to refuse to answer questions about the animal or even posts inside info that only one or two other people that are privy to the project will understand.
It's VERY poor and confusing advertising. State exactly what you are posting, if it is a teaser you are aiming for, explain the project and that there will be more info forthcoming once the animal or gene is figured out.
