Marlin is unmistakably a cat. The orange coat, the pounce, and the occasional decision to climb directly onto another animal’s head settle that. Still, nobody seems to have explained the usual feline job description to him. Marlin joined a home with several dogs when he was roughly five and a half weeks old, then began following them through a life built around boats, beaches, and fishing along North Carolina’s Outer Banks.
The dogs run toward the surf in this video, and the little kitten goes with them. He enters the ocean voluntarily, paddles through the water, and heads back toward shore without the frantic scramble most people would expect. The obvious question is not whether Marlin has secretly become a dog. It is why this particular cat is so comfortable doing something many cats work very hard to avoid.

Who Is Marlin the Swimming Cat?
Marlin belongs to Caroline Jarvis Hopkins and Mack Hopkins, and his story began on Hatteras Island. In Caroline’s account of his arrival, a friend delivered the kitten to the couple at the docks while they were loading a boat for a fishing trip. From there, water was not some strange place Marlin encountered years later. It was part of the scenery almost immediately, along with the family’s dogs, two homes in Buxton and Wanchese, and regular trips along the Outer Banks.
According to Caroline’s account of his early life, Marlin was already swimming in a creek and riding on the boat within days of arriving. He also played, chased, and roughhoused with the dogs at home. That history gives the video useful context: Marlin is not being introduced to open water for the first time and shoved in to see what happens. He is following familiar companions into an environment that has been part of his routine since kittenhood.
Do Cats Really Hate Water?
Many cats do object to getting soaked, but “cats hate water” is too broad to be a biological rule. Cats Protection notes that most feline coats are not highly water-resistant. Once saturated, the fur can feel heavy, restrict quick movement, and make temperature regulation more difficult. An unfamiliar splash, bath, or moving body of water can also remove the control cats generally prefer to have over their surroundings.
That still leaves plenty of room for individual variation. Some cats investigate faucets or play in shallow water, and a few willingly swim. Certain breeds are often associated with water-friendly behavior, including Turkish Vans, Maine Coons, and Bengals, although breed never guarantees that an individual cat will enjoy getting wet. Marlin is a domestic orange tabby, not a special aquatic breed. His comfort appears to be about Marlin.
Did Growing Up With Dogs Make Marlin Love the Ocean?
It is reasonable to think the dogs influenced what Marlin treated as normal, but the video cannot prove that they taught him to love water. Young animals learn from repeated, low-stress experiences, and Marlin had unusually early exposure to both water and canine companions. Watching the dogs enter the surf without alarm may have made the setting feel safer and given him something familiar to follow. His own curiosity and temperament still matter, though. Put another kitten in the same household and you might get a very different answer.
The better explanation is probably a combination rather than one magic cause. Marlin met the dogs early, encountered water early, and repeatedly experienced both without an obvious bad outcome. Eventually, chasing his companions down the beach and into the surf became another family activity. He did not need to believe he was a dog. He only needed to decide that following them was more interesting than staying dry.
Can Dogs and Cats Actually Become Friends?

Cats and dogs can form friendly relationships, particularly when introductions are early, gradual, and positive.

The old “fighting like cats and dogs” line has oversold the rivalry. A 2018 study of 748 mixed-species households found that most owners considered their cats and dogs comfortable with one another. A younger age when the cat met the dog was associated with a more amicable relationship, and the cat’s comfort appeared especially important in shaping how well the household got along.
That does not mean every pairing will work, and nobody should expect instant friendship. Temperament, a dog’s chase drive, the animals’ prior experiences, careful introductions, and access to separate food, resting places, and escape routes all matter. Cats and dogs also use some body signals differently, so time and calm exposure help them learn what the other animal is communicating.
Marlin had the early introduction working in his favor. The dogs were not strange intruders who arrived after his habits were established; they were simply there from the beginning. He remained a cat, but they became his companions—and, in this case, his very enthusiastic beach guides.
Should You Take Your Cat Swimming?
Marlin’s example is not an invitation to place an unwilling cat in a pool or carry one into the ocean. Cats Protection advises against submerging cats during routine bathing, and forced exposure can turn water into a frightening experience. A curious cat should be allowed to approach at its own pace, remain under close supervision, and always have an easy way back onto dry land. Open water adds currents, waves, boats, wildlife, and changing temperatures to the risk.
In other words, let the cat make the first move. Marlin had years of positive experience, familiar people nearby, and a group of dogs he already trusted. That is a very different setup from dropping a house cat into the deep end because one orange celebrity made it look fun. Some cats really do enjoy water. Most would prefer that we admire those cats on video and leave the bathtub out of it.
