What Are The Health Benefits of a Cucumber For a Tortoise?

It is a fact that most of the nutrients portion in cucumber is occupied by water that is up to 96%. The remaining 4% include fibre, vitamins, calcium, and phosphorus. Therefore, it comes up among the most nutrient-deficient fruits.

However, cucumber offers several health benefits to a tortoise if given moderately. Let us first have a look at the nutritional content of a raw cucumber of 52 grams.

Water49.5 grams
Vitamin C1.5 mg
Vitamin A54.6IU
Fiber0.3 grams

The health benefits that a tortoise can get from feeding a cucumber are as follow:

1 – A source of hydration

Tortoises need plenty of water to maintain their optimum hydration state for normal body functioning. Moreover, pet tortoises tend to get more water from the food they feed. Therefore, watery fruits like watermelon and cucumber are the best treats to meet water requirements due to their higher water contents.

Dehydration is a severe concern of pet tortoises due to the stress of captivity and loss of humid and natural habitat. In such circumstances, you have no choice but to ensure the provision of plenty of fresh and chlorine-free water to keep them hydrated.  

Cucumbers lend a helping hand in maintaining the average water level in your pet tortoise in hot summers and avoiding the risk of otherwise fatal dehydration.      

2 – A Battery of vitamins

Vitamins are must ingredients in a tortoise diet (in fact, every animal, including humans) for optimal growth of shells and bones. In case of vitamins deficiency, a tortoise may lead to developing several skeletal and health abnormalities. Therefore, tortoises in captivity must need special attention to avoid such life-threatening abnormalities.

Cucumber contains nothing but water and a battery of essential vitamins that are much needed for normal metabolism. The presence of vitamin A and C are evident in a cucumber that is a blessing for your tortoise.

Just have a glance at what the deficiency of essential vitamins may bring about in your docile and lovely companion. 

Vitamin A deficiency

  • Swelling of limbs because of liver failure
  • Inflammation of eyelids
  • Mouth’s horny part thickening
  • Weakness of immune system
  • Thickening of skin
  • Greater chances of infections 

Vitamin C deficiency

  • Impaired wound healing
  • Internal bleeding
  • Anemia
  • Neurological symptoms

However, there are the least chances of vitamin C deficiency in tortoises due to the ability of their body to synthesize it in the gut. It’s all about the presence of a healthy gut biome that assists its synthesis.              

3 – A package of minerals

Cucumber is not a rich source of nutrients and minerals; however, it provides some of them, like calcium and phosphorus. Minerals like calcium and phosphorus play a role in healthy skeleton formation. 

So, you can offer a healthy skeleton and shell to your tortoise by ensuring the provision of cucumber treats along with other nutrient-rich fruits.

What Are The Best Ways To Offer a Cucumber To Your Tortoise?

The best way to serve a cucumber to your tortoise is whole or sliced cucumbers mix with other ingredients like vegetables and fruits. This will delight your tortoise. Grating of cucumber over your tortoise’s favourite greens is also appreciatable.

There are a few useful tips to remember when serving cucumber to a tortoise:

  • Always try to provide cucumbers that are grown organically
  • Don’t forget to wash cucumbers before offering properly
  • It is best to mix with other fresh food ingredients like fruits and veggies
  • Offer cucumber to your pet tortoise during a suitable time, i.e., afternoon

As a pet owner, it is your duty to keep an eye on the health of your beloved pet tortoise. In case you neglect at least one of these tips, then you are inviting trouble and may be harming your pet as well.

Serve the cucumber in its most natural form without any additives. The addition of salt, spices and even lemon seems to bring undesirable side effects in your tortoise. It is always best to offer a plain cucumber treat to your pet tortoise.

Can My Tortoise Eat Cucumber Leaf?

Some owners may think that leaves also provide enough nutrition and may be a good addition to their tortoise’s diet. However, such thoughts are not correct as the leaves of cucumber are not a good option for your pet.

The absence of nutrients and vitamins in the leaf makes it as an unfavourable food for tortoises because the leaf contains more water than any other component, including vitamins. Foliage from a cucumber plant is not a good option for your pet tortoise.

Stick to only feeding your tortoise with the cucumber and not the leaves.

Can You Use Cucumbers To Hide Medication?

Yes, if your tortoise has enough stubbornness to refuse any medication, it will be best to hide them in a cucumber – their best snack. However, you can also use other treats for the same purpose, like tomatoes and oranges.

Wether or not it is a good idea to hide medication is a question we get quite a lot. The answer is that it is not a good idea. It is often not easy to get your tortoise to eat its medication, even though it is important for them.

Because of this it may well be the best option to trick your tortoise by concealing the medication. It might even be necessary. If your pet requires medication you cannot risk it not getting it all.

Cucumber is one of the best fruit treats for your tortoise that is scientifically proven safe. Although it is safe for almost all tortoise species, few are prohibited, like Grazing tortoises and Mediterranean tortoises. Cucumber is not a particularly nutritious ingredient but offers certain other benefits like avoiding dehydration.

Are Tortoises Picky Eaters?

Tortoises are not picky eaters and they will most likely enjoy a cucumber, but you should still be mindful of the following. Always try to provide organic grown cucumbers that have been washed before serving them to your pet tortoise.

The leafs of a cucumber plant are not great for feeding purposes because they don’t offer much nutrition and contain more water than vitamins, minerals etc., while foliage from the plant isn’t a good option for your tortoise either. 

As with many other vegetables you can feed cucumbers to your tortoise in their most natural form without any additives. The addition of salt, spices and even lemon seems to bring undesirable side effects in your tortoise.
