Can Hermann Tortoises Eat Kiwi? (+Other Fruits to Avoid)


Can Hermann Tortoises Eat Kiwi

Hermann tortoises and their dietary preferences can be very strange, sometimes tortoises will eat everything that is in front of them (even if they shouldn’t) and other times they will become some of the pickiest eaters in the world. But how do they feel about kiwi?

Hermann tortoises can eat kiwi, but not too much. Like most fruits, kiwi contain phosphorus, which can be harmful to tortoises in high quantities.

Kiwi are good and bad at the same time. They are good due to the high quantities of vitamins they contain, like B6 and C, but at the same time they are bad due to the high amount of phosphorus.

If you can manage the calcium:phosphorus ratio, you can safely give your tortoise kiwi. So let’s start our discussion with that, after which we will see how much and how often you should give your tortoise kiwi.

The Calcium Phosphorus Ratio of a Banana

Almost all fruits contain calcium and phosphorus. And as a result, most of them have a calcium to phosphorus ratio. So let’s take a look at what calcium does for tortoises, what phosphorus does for them and what is a good calcium to phosphorus ratio.

Calcium is essential for every animal in this world that has bones. And since the shell of a tortoise is made out of bones, calcium is even more important for tortoises than for any other animal. Fruits are one of the main sources of calcium that a tortoise has, so making sure that you feed them vegetables with high amounts of calcium is important.

For humans, phosphorus is a very important mineral that helps filter waste, repairing tissue and cells, etc. But for tortoises, phosphorus is not that great. Phosphorus is what gives tortoise shells a little flexibility, which is great because this little extra flexibility makes them more resistant to bites and other types of impact. But too much phosphorus can also make the shell a lot softer, and as a result much weaker when it comes to defending the tortoise from predators.

In short, we can say that calcium is great for tortoises and phosphorus is not so great for tortoises in high quantities.

Most fruits have a calcium to phosphorus ratio, this ratio can be 1:1, 2:3, 5:2, 1:2, etc.

A 1:1 ratio means that the amount of calcium is equal, or almost equal, to the amount of phosphorus. So a vegetable with this ratio is not that great for tortoises, but it’s not harmful either. But if possible, such a vegetable should be avoided.

A 1:2 calcium to phosphorus ratio is really bad, there are not many vegetables with this ratio, so don’t worry too much about them. Just remember that if a vegetable has more potassium than calcium, you should keep it away from your tortoise.

A 2:1 ratio is great, and this is what you should be aiming for. If the ratio goes higher, it’s ok, but ideally this is the ratio that you are looking for.

Kiwi has a 1.1:1 ratio, which is not ideal. But at the same time, it’s manageable. And of course depending on the way the kiwi have been grown the ratio will look a little different from, but overall it should still be in the same area.

Here is a short list with some fruits that have a high phosphorus content and should be avoided in large quantities:

Here is a list of some of the most common vegetables and their Calcium to Phosphorus ratio:

  • Grapes – 1.4:1
  • Apples – 1.1:1
  • Pineapple – 1:1
  • Mango – 1:1
  • Pears – 0.8:1
  • Strawberries – 0.8:1
  • Guavas – 0.8:1
  • Cherries  – 0.8:1
  • Apricots – 0.7:1
  • Blueberries – 0.6:1
  • Kiwi – 0.65:1
  • Peaches – 0.5:1
  • Bananas – 0.3:1
  • Plums – 0.3:1

How Much and How Often You Should Give Your Hermann Tortoise Kiwi

While kiwi don’t have the best calcium phosphorus ratio, they still have a lot of beneficial vitamins, so they shouldn’t be excluded from the diet of your tortoise entirely. They should be treated more as a snack or reward than a staple in their diet.

I feed my adult tortoise about one banana every few months. And I would recommend you to do the same.

If your tortoises have a balanced diet, a couple of kiwis now and then won’t do them any harm, and it will allow them to benefit from all the good parts of the fruit.

Now let’s see what are the benefits of a banana for a tortoise.

The Benefits of Kiwi for Hermann Tortoises

Kiwi are full of vitamins that make them worth feeding them to your tortoise, despite their not so great calcium phosphorus ratio, but the most abundant and important are Vitamin B6 and vitamin C.

Vitamin B6 plays a very major role in energy conversion. To put it simply, vitamin B6 helps tortoises remain energetic throughout the day, without it, they will feel tired constantly. Vitamin B6 can be mostly found in berries.

Vitamin C, as you know, plays a very important role in the maintenance and development of the bones. And since almost the entire body of the tortoise is covered with a shell, which is made out of bones, vitamin C is essential for them. Lucky for tortoises, vitamin C can be found in most fruits, so they don’t usually have deficiencies.

What to Do If Your Tortoise Doesn’t Eat Kiwi

The first thing that you have to do is to determine the cause. And there are two possibilities.

One possibility is that your tortoise simply doesn’t like kiwi, one of my tortoises is exactly the same.

In this case, you could reduce the amount of food that you usually give it and replace it with kiwi. But I would advise you against this. While a few kiwis are good for them, they can still get the same benefits from other fruits.

If your tortoise doesn’t like kiwi, you shouldn’t force it to eat them. As it’s just a matter of taste. Every tortoise is different, some will like kiwi, some won’t.

But if your tortoise refuses to eat any kind of fruit, then you have a problem, as fruits can’t be completely removed from their diet. If this is your problem, you should start replacing some of the food that you usually give your tortoise with fruits. And it shouldn’t take more than two or three weeks until your tortoise will start eating fruits.

The second possibility is that your tortoise is too young. It’s not uncommon for baby and juvenile tortoises to not eat certain fruits. When tortoises are at those life stages they are growing a lot faster than adult tortoises, and to grow this fast they need a lot of protein that they get from greens like: spinach, watercress and cabbage. Eating kiwi, while it will keep them from starving, it won’t do them too much good at this point.

If your tortoise is young, then it’s perfectly normal that it won’t eat kiwi. Just wait until it reaches maturity, then you can try again to feed it kiwi.

Final Thoughts

Hermann Tortoises will normally eat kiwi, as well as other fruits. Just be careful not to give your tortoise too many kiwis, since they can be bad if consumed in excess.
