Are Foxes A Danger To Tortoises?

Last Updated on September 18, 2023 by Samantha Harris

Foxes are cunning apex predators with sharp teeth, dexterous bodies, slender snouts, and claws.

Foxes are a serious threat to tortoises. Hungry foxes, especially new mothers, are deadly hunters, while tortoises are slow movers and vulnerable to predators.

While tortoises can retreat into their shells and burrows, foxes use their sharp claws and slender snouts. However, if a tortoise is kept in a secure enclosure, foxes may ignore them in favor of easier prey.

Supervise your tortoise outside and bring it inside at night because foxes avoid humans.

Are Tortoises Safe from Foxes?

Tortoises have many defenses against predators, but foxes are agile and cunning animals.

While the likelihood of a large tortoise species being harmed by a fox is low, the odds are never zero. Owners must take precautions if their tortoises are kept outside where foxes can access them.

Here are factors that can make a tortoise more vulnerable to foxes:

Supervision vs. Free-Range

If a tortoise is kept outside full-time, there’s a higher risk of fox attacks. Foxes are more likely to avoid humans than tortoises and may stay away if you’re present.

If you have a large fox population near your home, supervise your tortoise when it’s outdoors. For tortoises that are kept outside, keep them contained in an enclosure.

Daytime vs. Nighttime

Most foxes are nocturnal creatures and come out to hunt their prey at night. The odds are low of one exploring during the day or visiting your busy yard.

Even if a fox emerges, it’s unlikely to hunt since it’s at a disadvantage in the light. That makes daytime an ideal time for tortoises to explore, forage, and play in human presence.  

However, there are dangers if you keep your tortoises in an outdoor enclosure at night. It’s more likely that foxes will come out and hunt small animals, like tortoises.

Sealed or Open Enclosure

Ensure all outdoor enclosures have an overhead lid or are fully secured. If it’s kept exclusively outside, your tortoise shouldn’t be allowed to leave its enclosure at dawn, dusk, or night.  

A well-covered and secured enclosure can keep tortoises safe from foxes at night. Foxes are cunning creatures, but they probably won’t go out of the way to break into an enclosure for a meal.

A fox would much rather chase its prey or dig it out without putting in the extra effort.

Size of Tortoise

The bigger, heavier, and broader the tortoise, the less likely a fox will target it as prey. Of course, smaller tortoise species are most vulnerable to foxes.

If you own small tortoises, keep them in a secured enclosure at night and supervise them when they’re outdoors. If you own large tortoises, they’ll be okay with fewer precautions.

After all, tortoises can retreat into their shells, and foxes will have little recourse against their large bodies.

Can A Fox Kill A Tortoise?

Foxes can kill a tortoise because they have sharp teeth and claws that can get inside the shell of some tortoises. Their bite strength won’t crack most tortoise shells, but they can shake them.

A hungry fox is more of a threat to your tortoise than a well-fed one.

The Journal of Wildlife Management reports that foxes feed on rodents and rabbits. However, a hungry fox with kits to feed is likely to hunt any small animal.

Foxes usually give birth during the spring and summer, so they’ll have kits to feed until September or October. During this time, any foxes that catch the scent of a tortoise are likely to kill it.

Will Foxes Eat Tortoises?

Foxes have evolved to prefer eating rodents and rabbits, but these food sources aren’t always available.

According to the University of Sydney, while foxes don’t usually hunt reptiles and amphibians, a hungry fox will eat anything it can.

If a fox finds a tortoise in someone’s backyard, it’ll attack, kill, and eat it.

How Tortoises Protect Themselves

Mature tortoises are large and heavy with thick, armored shells. These factors alone can deter foxes from attacking and killing a tortoise.

Even so, tortoises have ways to protect themselves from fox attacks:


Tortoises have bone and keratin-based shells, two highly resilient materials. The shell is a part of the tortoise’s skeletal structure and is covered with scutes, which are hard plates across the back of the shell.

Together, this creates an armor that’s hard to penetrate or grip.

In larger species, this is paired with their body weight, making it difficult for foxes to lift or carry off. The only recourse a fox would have is to reach inside the shell.

Depending on the species, tortoises retreat into their shells because they’re resilient against damage and hard to pry open. This would protect the tortoise’s softer body parts, like its head and legs, against a fox.

Tortoises that lack this bulk tuck their legs and head under the lip of their shells. Of course, this leaves them more exposed but still makes it difficult for foxes to harm their delicate body parts.

Foxes prefer easy meals. Unless they’re starving, they’ll likely give up on a tortoise. However, hungry foxes may doggedly harass a tortoise until they’ve caused significant damage.

Burrowing is a way for tortoises to create a comfortable home and defend against predators. When a tortoise senses danger, it’ll retreat into its underground burrow.

The tortoise may even try to burrow into a soft substrate in desperate situations. However, since foxes are also burrowing creatures, it’s unclear if this tactic will be effective.


Tortoises have sharp beaks that can deliver a powerful bite.

The tortoise may hide within its shell and move its head to bite a predator when threatened. This can harm a fox if the bite force and placement are right.

Of course, foxes have sharper teeth and a powerful bite. However, one strong bite from a tortoise to the fox’s snout can severely injure it enough to cause it to give up.


It is no coincidence that tortoises are found with various shapes, colors, and patterns on their shells.

These are designed to blend in with the foliage of their natural habitat, which camouflages the tortoise from being seen by predators.

Of course, the effect of camouflage is even greater when combined with burrowing. It could trick a predator, like a fox, into thinking that the tortoise has got away or escaped.

This is made more effective by a tortoise’s ability to lie completely still for a long time.

Foxes are a danger to tortoises because they’re apex predators, while tortoises are prey animals that are slow, docile, and often small in size (for pet species).

For this reason, implement safeguards to ensure your tortoise never has to defend itself from a fox. While tortoises have many defenses to deploy, the chances of serious injury and death are ever-present.
