Yep, wife rescued a box turle years ago. It lived with us in it’s own little space for quite a few years, tolerating kittens hunting it. Wife read up on them and built a shelter for her to hibernate. She did.
They’re humble little animals. I rescued one from my Lab years ago, he was carrying the turtle around in his mouth, and had chewed the edge off the turtle’s shell in a few spots. Took it to the wildlife vet, they assured me that it would be fine and would be released. Said they patched them up all the time, most often due to encounters with lawn mowers.
In CT, you’d be arrested and your house & car confiscated.
