hello, today i saved a red ear slider from being released into the wild. He's about 4 years old and i don't think he has been taken very good care of. It seems like he is almost shedding skin from his feet and legs, not his shell. It looks weird and i'm really new to turtles. Has anyone ever seen this? also, I was looking at turtle docks and they are so dang expensive for a few suction cups and a piece of styrofoam. What would be an alternative basking area that would be cheaper than $30+? thanks!
