My eight year old grandson has been begging me for months to get in with the rays and feed them so i finally gave in to him and put him in the shower to srub down (soapless) and rinsed all the fabric softener out of a pair of shorts and put him in. It was really different than I expected, the rays came right up to his feet and i assume sniffed them and ate from his hand and really seemed like they liked him being there allthough they didnt tell me that for sure. Well anyway he got cold within 5 minutes so he didnt wear out his welcome.
