I believe you are right about the frog choosing their owners. My two boys are both wild caught and they love me to pieces. They will sit at the front of the tank on their branch and beg to get out by watching me every time I walk by them. And once I open the tank, they will jump right on to me and sit there for hours perfectly contented. I love them SO much! I never thought I would get that much attention from wild caught frogs, but amazingly I did and I am thrilled! I am sorry you are allergic to mammals That really blows... But yes, frogs are wonderful little guys! Here are my babies waiting patiently to be fed and playing in the clover out front. They get all kinds of attention and they love it here with me! I have even had a frog get away from me out side and she came home to us a few weeks later! She jumped up onto my husbands leg when he went out to take out the trash! They are truly amazing!
