Recently in Florida, a dolphin was released back into the wild and was attacked by sharks soon there after. The dolphin wasn’t killed by the sharks however, but its wounds were severe.
This reminds me of my pet cat when I was 12. His name was Arnold (after the Governator) and he was tough as nails; he was an outside cat. My mom had him neutered and he was roadkill within a week. Sad, but true.
