I have A Red Ear Slider turtle and want to know if i can keep it outside by making a rectangle shape in the dirt and filling that in with a large container and making it flush at the end, so it can go in and out when ever it wants in an area in my backyard. It will be secured and were the sun also hits. I will also put shade for it. I want to do that because I have a tank in side my house and it does not want to bask at all it is always in the water and yes it can go up to bask any time it wants but dont not choses to.
