Anyone know how old do sliders have to be til they're mature? I have a female that hatched February 2016, she's about 8". For a few days she's frantically trying to get out of the pond and shows no interest in food. She's been getting out on the basking rock and kicking her back legs almost like she's trying to scratch her tail. In fact she's done it so much she's rubbed her feet raw on the rock and they started to bleed a little. Is it possible she wants to dig a nest at such a young age?
