What is Poisonous to Hedgehogs?

In the wild, hedgehogs enjoy a varied diet and consume everything from plants to small mammals. However, wild hedgehogs have better immunity. With domesticated hedgehogs, owners have to be careful about what they feed, as some foods can be harmful to them. So let’s take a look at what is poisonous to hedgehogs:

Some foods which are poisonous to hedgehogs include chocolate, avocados, grapes, and raisins. 

Hedgehogs are sensitive animals, and feeding them the wrong thing can have severe effects on their health. In addition, hedgehogs also tend to hide their illnesses. Therefore, you will not notice that your hedgehog is not well until the illness aggravates.

The most common sign of feeding the wrong to your hedgehog is diarrhoea, which further weakens their immune system, making them susceptible to other dangerous diseases. 

So, What is Poisonous to Hedgehogs?

While some foods can merely cause a hedgehog’s health to decline, others can kill them. Hence, it is important to monitor your hedgehog and see that it does not eat anything that can threaten its life. Here are some food items which can kill hedgehogs:

Citrus Fruits 

One of the foods which can kill hedgehogs is citrus fruits. It is not recommended to give your hedgehog citrus fruits because they are highly acidic.

A hedgehog’s stomach cannot handle the acidity, and consuming citrus fruits like oranges or lemons can cause its digestive system to become destroyed. Your hedgehog will go through a lot of pain after consuming anything citrusy.

Many sources on the internet can lead you to believe that avocados are not bad for hedgehogs. However, as pet owners, it is our responsibility not to take such risks and put our hedgehogs in pain. Avocadoes are known to be poisonous to hedgehogs, and consuming them can potentially kill them.

Therefore, you must keep all your avocadoes away from hedgehogs and not feed them even as a treat. 


Grapes may make a wonderful snack for you, but for hedgehogs, they can become their nightmare. Grapes are toxic to hedgehogs and can cause severe kidney and liver damage.

In addition to grapes, you must also avoid giving raisins to your hedgehog because not only are they a choking hazard, but they also contribute to liver and kidney damage.


Another food item that you need to be wary of is mushrooms. Not all types of mushrooms are harmful to hedgehogs, but some of them can be. Therefore, if you are not too sure whether a mushroom can be poisonous or not, you must refrain from giving it to your hedgehog.

In addition, chocolate is packed with sugar, and hedgehogs are prone to gaining weight because of their small bodies. Therefore, you must avoid any sugary and fattening food as hedgehogs are likely to become obese and contract diabetes. 

Dairy Products 

Many people are not aware that hedgehogs are lactose intolerant and, therefore, give their pets milk or yoghurt. Consuming any dairy product is harmful to hedgehogs and causes them to have diarrhoea. Moreover, hedgehogs will become weak and susceptible to contracting more diseases.
