I have to wonder what the dolphins were thinking. They were evidently intrigued by the cat. Once while on vacation in NC, I saw dolphins working in conjunction with a golden retriever. The dolphins would parallel the beach pushing the bait fish in towards shore- the golden would splash into the water chasing the bait fish back to the dolphins who then caught and ate them. This happened every morning along the beach in Hilton Head where we were vacationing for a week.
