I have had, for reasons unknown, and rather mysterious, bad luck with panthers.
Have had 3 in row die from inherited problems.
I now have 2 panthers, one is abnormally small, and seems to have a problem breathing through his nose. He has not shown any classic symtoms of any infections, so may have just been born this way.
The other panther is large and healthy. I got him from Komeleons.
So, based on my experience, and not saying the other 2 breeders are bad, if I were to buy another panther it would be from the only place I had luck with.
But that's just my own strange experience, I am sure any of the site sponsors would be equally fine to buy one from.
PS. I would recommend buying from a small scale breeder who does not do it for a living.
They tend to be much more pampering, handling, fussing over their babies. Large scale breeder do not have that kind of time to
spend on each individual baby. So, small breeders handle the chams much more, and you are more likely to get a cham that is
already used to being handled, which goes a very long way in taming them as a pet.
One more thing, before you buy from anyone, do yourself a favor and look them up on Fauna's BOI (board of inquiry) to see what feedback (if any) they
have gotten from their customers.
