I think with geckos being given away it more of getting bored with the little sticky toes than not being able to handle it. It is a valid observation, and I agree that too pany people are probably breeding them. But it is not an animal that will outgrow you. I think getting bored witht he animal is the driving factor. As far as the massive amount of breeding. Geckos are often a first lizard and they are easy to breed. Too many people with pipe dreams of making a living breeding herps. It is few and far between that herps are the sole source of income.
I planted some bird seed. A bird came up. Now I don't know what to feed it.
