Cuban Tree Frogs...

[Cliygh and Mia 2]

Perhaps what you could do is cull a amount of them humanely, and sell a few of them on a site like faunaclassifieds or kingsnake? I'm sure someone would be able to take care of a few, but like you said, more than probably 30 will be too much for any one person to handle, not to mention their invasive status in the US...

I love frogs myself, but Cuban tree frogs and other invasives are detrimental to the native frogs and other wildlife. By all means keep a few as pets, but the responsible and ethical thing to do would be to euthanize the rest.
