I don't agree. You pay, let's say, $200 for a little brown baby panther, not really knowing exactly what you're getting (because we know they don't always turn out like carbon copies of their fathers). Why wouldn't you then sell the same animal for more when their full potential is realized? Now you can see exactly what the animal looks like, it's not an investment that you hope turns out how you want it to. I think that selling an adult panther for more makes all the sense in the world, you now have certainty if you're a breeder, not "fingers crossed!"
And what is this used thing? It sounds like you think all re-homed animals are "ruined" somehow, like they should be worth less just because they had a previous home?
To everyone that is on here who is arguing against panther prices and hates the species anyway, what's the point? You just sound bitter, honestly. If you don't agree with it, then don't do it. I don't like cats, so I'd never pay anything for a cat that I could get practically for nothing at a shelter. But I am, as we speak, sending a woman a nice check for a pure bred dog that I do like, and want very much. So to each their own, if you don't agree with it or want to support it then just don't. Keep working with the species you do like, and who knows, the market may even itself out in time.
I still don't think panther prices are that extravagant, compared to what other species go for CBB. $150-200 for a panther, $250-300 for a Meller's, $100 for a carpet... etc.
