Highly-poisonous to non-poisonous – a brief overview of the toxicity content

Since a large number of decorative plant families are attributed to succulents, this type of plant cannot generally be defined as poisonous or non-poisonous. The following brief overview provides information about some of the most famous succulents:

Thick-leaf plants (Crassulaceae), such as jade plant, stonecrop or Kalanchoe: non-poisonous to slightly poisonous

Midday flowers (Aizoaceae), like living stones: slightly poisonous in large quantities

Amaryllis (Amaryllidaceae), like knight’s star: highly poisonous

Spurge family (Euphorbia), like Christmas Star: poisonous to very poisonous

All cacti are pet safe succulents. However, the long, pointed thorns can cause skin injuries that, if left untreated, can develop into dangerous infections.

Succulent Safe for Reptiles

A terrarium is a natural oasis that looks good in any room. Terrariums are essential for reptiles like bearded dragons to live in perfect environmental conditions.

If you choose to upgrade your desert terrarium with living plants, there are a few things to keep in mind. Succulents are found almost everywhere in the world, but certain plant families are naturally found only in certain regions. For example, cacti live in America (apart from the poached cactus figs in the Mediterranean), as do agaves. Aloes and delospermas, on the other hand, are mainly found in Africa. Euphorbias are present all over the world. So if you intend to create a true-to-original habitat, pay attention to where your reptile comes from and which plants are native to it.

The next important point is the risk of injury. Many cacti have pointed thorns (=converted leaves!), where one can sting very sensitively, especially when the free space is small. While you may have considered many different types of plants for reptiles, not all of them are completely safe. Some are even poisonous! Other plants contain toxins that protect them from eating. In the professional world and among terrarium lovers, some people do not yet quite agree whether the sap of the Euphorbia is also toxic to reptiles. Opinions differ widely here. Personally, I would not risk anything.

Other succulents, such as some representatives of the ice plants (Aizoaceae), contain alkaloids, which should be dispensed with. Many water-storing plants, such as agaves, opuntias, and sedums contain oxalic acid, which should not be consumed in large quantities. How big a “large” quantity is, however, remains to be seen.

And most importantly, you should do without plants from construction and supermarkets. These are often strongly treated with insecticides and herbicides and thus cause undesirable side effects.

What to Do if Your Pet Ingests a Succulent

Because there are many varieties of succulents, the most crucial thing to do when your pet ingests a succulent is to identify the succulent and call for animal poison control.

You can also ask your local veterinarian for advice, although, if your veterinarian is not familiar with toxic succulents, you may need to contact an antivenom center for advice. If poison control suggests treatment, they will issue you a case number that will allow your vet to consult with the toxicologist about any treatment at no additional cost.

Keep your Pets Happy and Safe

If you keep succulents at home, make sure they are not within your pets reach. By keeping toxic succulents in hard-to-reach places, you can avoid potential risk to your pet. If your pet does end up eating a succulent, call the animal poison control to see if treatment is necessary.

And most importantly, you should do without plants from construction and supermarkets. These are often strongly treated with insecticides and herbicides and thus cause undesirable side effects. Numerous reported cases have highlighted the harmful effects of herbicides like Roundup on both animal and human health. Studies have provided evidence of the development of different cancer types resulting from exposure to Roundup, such as non-Hodgkin’s lymphoma, pediatric brain cancer, and several other illnesses.
