Hey, TypingMonkey
Obviously, frogs don't have the capacity to be "tamed" in any sense of the word as applied to, say, dogs, cats or any other animal that we typically speak of becoming accustomed to owners or visitors. However, I can definitely say that even after nearly three months of raising my Birdo (I suspect it of being C. cranwelli rather than C. ornata), the frog has become more accustomed to my feeding it or petting it (I use my middle or index finger and lightly stroke down the back). In fact, the frog appears to be able to distinguish between my presence and that of my roommate or suitemates.
