If you do keep it to be released at a later date, you DO have to have a permit for releasing it.
Also, coyotes don't naturally live in South Carolina...they were brought in a few years ago. But I do agree that "can" doesn't mean "should" and it is a wild animal. Not ment for domestication. If you keep it, YOU are responsible. If it bites or attacks a person or other animal, that's all on YOU. They are considered pests for a reason...pests, not pets. Please let them go to a rehabber or take them back to where you found them!
