10 Ways To Keep Cats Away From Your Fish Pond

Cats are curious, and a pond full of moving fish is hard for them to ignore. Their hunting instincts do the rest, so a cat can quickly turn your pond into a hunting ground. They can also fall in and drown.

Key Takeaways

• Protecting a pond means changing the area around it and using specific deterrents.
• A mix of physical barriers, natural repellents and water or sonic deterrents can effectively dissuade cats.
• Knowing why cats are drawn to the pond helps you pick the right deterrent.

How To Keep Cats Away From Fish Ponds

There are several ways to keep cats away from a fish pond. They fall into physical barriers, plants, scent repellents, and sound or water deterrents. Here are the main ones.

Physical Barriers

Cats are persistent, but a few physical barriers can keep them off your pond. Nets, fences and rough surfaces all help.

Pond Covers and Netting

Pond netting is one of the simplest options. It works well and needs little upkeep.

Buy thick netting and let it extend a couple of feet past the pond’s edge. Anchor it with metal pegs so cats can’t squeeze underneath, and keep it taut, since sagging netting can be a hazard for wildlife and pets.

A cat-proof pond cover that blends in with the garden is a discreet option.

Some pond covers are solid metal frames with no netting in between.

They’re heavy-duty and designed to stop children and dogs falling into a pond, but the gaps in the frame may be big enough for a cat to squeeze through. Adding netting to one of these works better.

Fencing

Chicken wire or a solid wooden fence can work very well.

With chicken wire, make it tall enough that even an agile cat gives up. With a fence, check there are no gaps.

A raised, rocky edge or a low fence may be enough for less adventurous cats.

Sharp and Uneven Surfaces

Cats dislike uncomfortable ground. Jagged decorative stones or rocks around the pond make a poor landing pad for paws.

Prickly plants do the same job and look good too.

Check that any plants you choose are non-toxic to cats and safe for the pond.

Repellents

Cats have sensitive noses, so scent is a good way in. Plants they dislike make the area less appealing.

Plant Selection

• Citrus: Cats typically dislike the smell. Scatter lemon, orange or grapefruit peels around the pond.
• Aromatic herbs: Lavender, rosemary and lemon thyme all help, as cats avoid strong herbal scents.
• Rue: Known for repelling cats.
• Eucalyptus: Cats generally dislike its pungent smell.

Other Scent-Based Repellents

Scent-based repellents deter cats without harming them or the environment, because cats have a strong sense of smell and certain aromas keep them away.

Citrus and Herbal Deterrents

Citrus peels from oranges or lemons are not to a cat’s taste.

Scatter fresh peels around the edge of the pond and the strong smell works as a natural deterrent. Certain herbs do the same job.

Lemongrass planted around the pond, or lemon verbena sprinkled there, makes a barrier curious cats won’t like.

Pepper Repellents

Cats don’t like pepper at all.

Cayenne and black pepper can be sprinkled around the pond to make it unpleasant to walk through. Go easy with cayenne in particular, because a little goes a long way. Reapply after rain or watering.

Water Deterrents

A bit of surprise can work well too, and water does it without hurting anyone.

Motion-Activated Sprinklers

Motion-activated sprinklers wait until a cat wanders close to the pond, then give it a blast of water. It sends them running.

They’re easy to set up, and you can adjust the sensitivity and range so they catch cats and not your guests.

Water Guns and Blasters

If you’re around, a water gun or blaster does the same job by hand.

A quick, precise squirt of water is enough to surprise a cat. It doesn’t need to be harsh.

Sonic and Ultrasonic Solutions

Sonic and ultrasonic devices use high-frequency sound that cats find unpleasant, which encourages them to steer clear of the pond.

Ultrasonic Pest Repellers

Ultrasonic pest repellers emit high-frequency sound beyond human hearing that annoys cats.

How they work:

• Detect motion: The sensor triggers when a cat approaches.
• Make noise: A startling sound plays and scares the cat off.
• Bonus: Some devices pair the noise with water jets.

An ultrasonic pest repeller by the pond creates an invisible sound barrier. Your cat, or the neighbor’s, may decide the pond isn’t fun any more.

Installation tips:

• Place several devices around the pond for coverage.
• Check the device’s range when positioning it.
• Move them every so often so cats don’t get used to the sound.

Keep the devices running and in good working order. Cats are clever and persistent, and they will test them.

Why Are Cats Attracted To Fish Ponds?

It helps to know what draws cats to the pond in the first place. They’re curious animals with strong hunting instincts, and a pond appeals to both.

Hunting Instincts

Cats are born with a hunting instinct that compels them to stalk and capture prey, and it doesn’t depend on hunger. A well-fed pet cat still feels the urge to hunt.

Moving fish trigger that predatory behavior. It’s a built-in response that is hard to curb, but understanding it helps you protect the pond.

Curiosity and Prey Drive

Curiosity is hardwired too.

Cats investigate new sights, smells and movements, and a pond is a theater for the senses.

Live fish look like prey, which sets off the prey drive: the instinct to chase and try to catch anything moving.

Getting a Drink

Your cat may just be after a source of water to drink.

Cats are famously fussy about drinking water. No matter how many bowls or fountains you put around the house, they’ll end up drinking from the sink or bath.

That doesn’t stop at the front door. Like their wild ancestors, domestic cats like a natural water source, and a pond is one.

Final Thoughts

Keeping cats away from a fish pond usually takes a combination of methods.

Fences and netting keep cats out of the area, and repellents and scaring devices put them off trying.

It also helps to give your cat other things to do, such as scratching posts or toys. A bored cat goes looking for activities, and hunting your fish is one of them.

Frequently Asked Questions

How do I keep cats away from my fish?

Use physical barriers such as fences, netting or covers, plus natural or commercial repellents and visual or sound deterrents. Positive reinforcement training can also teach your cat to avoid the pond and give it somewhere else to play.

Will cats eat my koi fish?

They might. Cats are natural hunters, and the movement and colors of koi can make them look like prey. Barriers or repellents are worth putting in.

Can you have a pond with a cat?

Yes, but you need to protect both. Barriers, repellents or deterrents keep your cat away from the water, so it neither harms itself nor the fish. Training can also teach your cat to avoid the pond.

How do I protect my frogs from my pond with cats?

Use the same barriers, repellents or deterrents. Hiding spots in the pond, like submerged pots or safe zones for frogs, give fish and amphibians somewhere to escape predators.

Will my cat hurt my fish?

It can, if it sees them as prey or gets curious enough to jump in. Barriers, repellents or deterrents will protect them.

Are fish stressed by cats?

They can be. Fish may sense a predator nearby, and stress affects their health. Keeping cats away from the pond protects them.

Why do cats like fish if they are afraid of water?

Mostly their hunting instincts. Cats may not like being submerged, but they are generally good swimmers, and the movement and colors of fish attract them.

Why do cats go crazy for fish?

Hunting instinct. The movement and colors of fish can trigger a cat’s prey drive and make them excited or curious.

Do cats prey on fish?

Yes, especially outdoor cats with access to a pond. Barriers, repellents or deterrents will protect your fish.
