Hello. I had my garage up today while I mowed, and when I came in, there was a turtle sitting inside by my garbage can, just out of the sunlight. I picked him up, put him in my kitchen sink with just a tiny amount of water and a piece of celery, and now don't know what to do with him or where to put him. I don't think I want to build him a home outdoors, so should I just let him go outside near some plants and hope for the best? Thanks.
