Safe And Unsafe Plants For Your Hamsters To Eat Or To Be Around

Hamsters like to munch on anything they can get their teeth on. Eating poisonous foods can be a danger to them. They do not have the ability to vomit, which means Hamsters don’t have an easy way to get rid of ingested toxins. Therefore, it is extremely important to take care of what our little one eats.

Some plants are safe for our Hamsters, while others are toxic for them. Most plants that have components that are poisonous to our Hamsters need to be eaten in large quantities to be truly harmful. So, if your pet takes a couple nibbles of a flower that they shouldn’t eat, they’ll probably be fine, but if they eat the whole potted plant, then you may have to take action.

Now we know that certain plants are safe for our Hamsters to consume. However, the consumption of some plant also has side effects.

Also, it is important to learn everything about the plant before tossing it in as some plants are highly poisonous for our little ones.

Also, owners must be aware of the fact that plants or even any part of a plant alone cannot fulfill the nutritional requirement of our Hamsters. Therefore, it should be served as a treat only. Now, let us understand more about this topic without any further delay.

Are Plants Bad For Hamsters?

While certain plants make an excellent supplement for our Hamsters, it does not suffice the vitamins and minerals needed for their healthy growth.

Serving in moderation is the key. Overfeeding might lead to several health problems in them. Listed below are some of the health complications from which our Hamsters might suffer if overfed with the plants:

  • Obesity And Bloating: Overeating the plant parts can easily make our Hamsters obese. It might even lead to bloating in them. Most plants contain carbohydrates and unnecessary fats, making our Hamsters bloat, making them inactive and sick.
  • Digestive Problems: Plant parts are more like treats for our Hamsters. When overfed, it might lead to digestive system disturbances and imbalances.
  • Might Cause Diarrhea: Overconsumption of any plant might lead to our Hamster’s diarrhea, gas, and pain. Therefore, you should never serve your Hamsters more than the advised quantity.
  • Dental Health Problems: Overeating the plants might even lead to tooth and gum damage in our Hamsters. In some cases, certain plant parts may get stuck between their teeth and gums, leading to irritation.
  • Allergies: Some Hamsters may have an allergic reaction to certain plants. Continuous sneezing, difficulty in breathing, and itching are some of the common signs of allergies. If your Hamster is showing any of the above symptoms, it is advised to take them to a vet.

20 Plants That Are Safe For Your Hamster

Although some plants may seem safe for your Hamster to eat or be around, it doesn’t mean they should be given unlimited access.

While most safe plants are healthier than sugary treats, they should still be given to our Hamster in moderation and variety.

Safe flowers can be given in moderation but shouldn’t make up a large portion of a Hamster’s diet.

It’s also very important to pay attention to any fertilizers or pesticides used with the plants your Hamster is eating.

Many of the substances used for lawn and garden care are poisonous to our little pets. They can be much more toxic than poison plants, so pay attention to any chemicals you use to keep your garden and plants looking nice.

Hamsters can eat dandelions without any worries. Other parts like leaves, stems, and flowers are edible too.

Dandelions are packed with essential vitamins and minerals required by our Hamsters. Due to excess calcium and phosphorus, overfeeding could be terrible for our Hamster’s health.

Organic jasmine plants are considered to be non-toxic for our Hamsters. All the plant parts, i.e., the flowers, leaves, and stems, are safe for our Hamsters.

It is important to be careful that you don’t have a false jasmine plant. These plants called Carolina jasmine or yellow jasmine, are toxic to our Hamsters. These plants look like true jasmine, but they are characterized by yellow flowers and are unrelated.

9. Nasturtium

Hamsters love to snack on the nasturtium. Our little ones find the flowers extremely tasty.

It can potentially cause digestive issues with Hamsters, especially if eaten in large amounts.

Marijuana leaves might be toxic towards Hamsters, but the flowers and stems are poisonous and should be avoided.  

At the moment there is no evidence that eating marijuana leaves is fatally toxic toward Hamsters, but other pet species have been studied and show negative health impacts from ingesting the leaves and inhaling the smoke.

For this reason, it is best to keep any marijuana away from our little ones and avoid smoking in the same room as them.

13. Daffodil

Flowers with bulbs are all potentially poisonous for Hamsters.

This includes plants such as daffodils, tulips, bluebells, orchids, and many more. Unless you know otherwise, you should assume that the entire plant, not just the bulbs are toxic to Hamsters.

How Worried Should You Be About Poisonous Plants?

Poisonous plants can be a cause of concern for our Hamsters. However, if your Hamster only eats a small amount of those plants, they likely won’t suffer from significant negative side effects.

When Hamsters have enough safe plants to munch on, they’ll ignore other unsafe plants because these don’t taste as good.

However, as Hamsters cannot vomit, eating too much of something poisonous can cause severe illness.

Sometimes, indoor potted plants can be a particular danger to our Hamsters.

When Hamsters only have limited access to plants, their natural curiosity can take over causing the Hamster to nibble on whatever is available.

If that happens to be a poisonous plant, they may eat a lot before noticing. It’s best to ensure any indoor potted plants are safe for Hamsters or keep them completely away from your pet’s reach.

What To Do If You Believe Your Hamster Has Eaten A Poisonous Substance?

If you believe that your Hamster has ingested a plant or other poisonous substance, you should immediately call your vet for instructions.

Even if your Hamster has only eaten a nibble or negligent amount, your vet will likely instruct you to pay attention to your Hamster’s behavior to look for signs of feeling unwell.

It’s always best to call anyway because some substances are more poisonous than others and may require immediate medical intervention.
