Can Rats Swim? Surprising Facts About Rats in Water

Rats are known for being survivors, but many people wonder: can rats swim? The answer is yes. Rats are excellent swimmers! In fact, their ability to move through water is one of the reasons they’ve adapted so well to different environments, from cities to rural areas.

Whether you’re curious about wild rats or thinking about your pet rat, understanding their swimming skills can be both fascinating and useful.

Can Rats Swim

Yes, rats can swim, and they are surprisingly good at it. Their strong legs, flexible bodies, and survival instincts make them natural swimmers. Wild rats often swim across rivers, ponds, and even underground sewers to find food or escape predators. Some studies even show that rats can swim for hours without getting tired.

How Far and How Long Can Rats Swim?

Rats are not just quick swimmers—they’re also extremely enduring. Research has found that rats can swim continuously for up to 3 days under extreme conditions. On average, they can easily swim for several hours and cover distances of more than a mile. This explains why rats are found in unexpected places, even far from where you’d expect.

Do Rats Like Water?

Here’s an interesting point: just because rats can swim doesn’t mean they like it. Wild rats usually swim only when necessary, such as for food, survival, or escaping danger. On the other hand, some pet rats actually enjoy water play. With a gentle introduction, many domesticated rats find swimming fun, especially in shallow water where they feel safe.

Can Rats Swim Underwater?

Yes, rats can dive and hold their breath for a short time. They can swim underwater for up to 3 minutes, which is impressive for such small animals. This helps them explore tight, flooded spaces or escape predators. However, not all rats are comfortable with deep dives, especially pet rats that haven’t been exposed to water.

Why Do Rats Swim?

Rats swim mainly for survival and exploration. Here are the key reasons:

Searching for Food: Rats are opportunistic eaters. If food is across a stream, pond, or even through sewer water, they will swim to get it.

Escaping Predators: When chased by predators (cats, snakes, or even humans), rats use water as an escape route. Their swimming skills help them survive.

Exploring New Areas: Rats are naturally curious. They’ll swim to reach new territories, nesting spots, or safer shelters.

Migration & Survival: In floods or heavy rains, rats swim to relocate and protect themselves.

Are Swimming Rats Dangerous for Humans?

Yes, rats in water can pose health risks. They may carry diseases like leptospirosis, which can spread through contaminated water. If you notice rats in your area’s waterways, avoid direct contact with the water and keep pets safe. While rats are strong swimmers, they can also spread problems when they enter homes through plumbing or drainage systems.

Can Pet Rats Swim Safely?

Pet rats can swim, but safety is key. If you want to introduce your rat to water:

• Start with shallow water (like a small tub).
• Never force your rat into water—it should be their choice.
• Keep the water warm and clean.
• Always supervise playtime.

Some pet rats enjoy splashing around, while others prefer staying dry. Every rat has its own personality, so watch how yours reacts.

Can Rats Swimming up Toilets?

Yes, rats can swim up toilets – and it happens more often than people realize!

Strong swimming skills: Rats can tread water for over 24 hours and swim long distances through sewer systems.

Flexible bodies: Their skeletons are very flexible, allowing them to squeeze through tight pipes.

Climbing ability: Rats can push themselves upward in vertical pipes, even against flowing water.

When a rat is searching for food or shelter, it may enter the sewer, swim through drainpipes, and eventually pop out of a toilet bowl. This is especially common in big cities where sewer systems are complex.

How to Prevent Rats From Swimming Up Toilets?

• Install a toilet flap valve (rat guard) in the sewer line.
• Keep bathroom doors closed at night.
• Fix broken sewer pipes quickly.
• Ensure your toilet lid stays shut when not in use.

How Long Can Rats Swim Before Drowning?

Rats are incredibly strong swimmers with surprising endurance. Studies have shown:

On average, rats can swim for several hours without stopping.

In the experiment, some rats swam for up to 48–72 hours (2–3 days) before drowning due to exhaustion.

Rats can also tread water for over 24 hours, which shows just how tough they are.

Their ability to survive in water for so long is one reason they thrive in sewers, drains, and even flood zones.
