Oh, I love it! Amazing that they have such a wonderful and loving bond. :)
I checked out You Tube to find the source of the video because it was obvious the dolphins were in captivity. It was filmed at Theater of the Sea in the Florida Keys. I remember as a child we drove past the amusement park after, I believe, Donna had hit the Keys. The park was demolished & in a small swimming pool was one dolphin circling the tank. It is darling how the cat rubs his head against the dolphin's chin.
