You are getting good advice here, just want to say that I would let aly help here, let the owners go through her no kill shelter network on this, if they want them bad enough they will do what is necessary to get them back. I agree the whole thing sounds very suspicious, how did they get in that cart? Like when we recently found lucee whoever left her in those woods did not deserve to get her back. If you refer these supposed owners to her shelter I bet she will never hear from them......tom
