Plants That Are NOT Good For Your Animals To Eat

We are often asked what plants can turtles and tortoises eat. We Share Our Progress As We Build, Make Mistakes, Learn, And Grow.

Very little research has been carried out into poisonings in Chelonia, compared with that done on poisonings in humans, other mammals, fish, and birds.

In the absence of definitive research, we felt it was easier to create a list of plants that are NOT good for your animals…. and probably your kids too.

(That is a joke)

It is a fact that animals such as tortoises often don’t know which foods are good to eat and which are not.

We do find that tortoises can safely eat a wider range of plants than humans. As turtles can safely eat more plant varieties then tortoises. Evolution is an amazing thing.

How do I knowif my plant is poisonous?

If you do not know, ask someone or assume it is poisonous until proven otherwise.

Try to identify all the plants that you have in your garden or yard.  Make a list of their names and look them up on our website for a guide as to their safety.

Also, you may take a large cutting of the plant (including the flower where possible), to your local garden center or nursery and ask them to identify it for you.  Once your plants have been identified, always write their Latin names down alongside the common name.

This is important as sometimes different plants share the same common names and can only be accurately identified by their Latin name.

*Different plant lists may give varying opinions as to the safety of certain plants for reptiles.  It is, therefore, your own responsibility to learn which plants are toxic and may poison our animals.

What Makes Them Toxic?

Oxalates: these plants contain oxalate salts. Contact with the sap can cause burning, swelling, and pain. Treatment includes rinsing mouth and washing skin with mild soap and water. Monitor for difficulty swallowing and/or breathing and drooling. Monitor for irritation, swelling or blistering of mouth and oral tissues.

Toxic or Potentially Toxic: These plants can be toxic to varying degrees and should be considered with caution. Toxic effects can range from mild irritation to severe organ damage. Call poison control or your veterinarian if you think your pet ingested these plants.

Dermatitis: contact with sap can cause skin rash, itching or irritation. Rinse with water and if irritation persists, contact your veterinarian.

Unknown: Suspected toxicity but information incomplete. If contact or ingestion occurs contact poison control and your veterinarian.

Other Fascinating Poisonous Plant Facts:

As few as 20 holly berries would be fatal to a human child, but birds such as cedar waxwings, mockingbirds, American robins, etc. eat them just fine.

The Monarch butterfly, of course, is well-known for exclusively eating toxic milkweed in order to concentrate the toxins in its own body, rendering the adult butterfly bitter and poisonous to other animals.

Deer browse on plants like skunk cabbage and false hellebore.

One tiny bite of skunk cabbage would leave a burning sensation in the human mouth for hours.

Lots of animals eat acorns, raw, right out of the shell. Humans can eat them, but only after they’ve been washed repeatedly in water to remove the tannins – the nuts are toxic to us due to the high level of tannins, prior to that treatment (not to mention, too bitter to be palatable).

Deadly nightshade, aka belladonna is a plant that will cause hallucinations, delerium, and death in humans. Only two berries will kill a child, and 10 to 20 will kill a healthy adult. Eating a single leaf may prove fatal. Cattle, horses, goats, sheep, and rabbits munch it down with impunity (though many of our pets may be killed by it as well)

What to do if you think your animal might have been poisoned?

Always keep your veterinary contact details near your telephone as this will save time in an emergency.

Seek immediate veterinary advice

  If you know what your animal has eaten, take the plant or any packaging with you to the vet, as this will help him/her decide what the poison is and the type of treatment that your tortoise will need.

Urgent veterinary help is essential when showing symptoms of acute poisoning

The signs of poisoning do vary and can include some or all of the following:  respiratory distress, excess salivation, choking, vomiting, tremors, convulsions or paralysis. 

As death may occur as a result of poisoning, ensure there is no delay in getting your tortoise to a specialist reptile vet for immediate treatment. Some poisons work quickly, with catastrophic effects, and some work slowly, causing damage as they gradually accumulate in the body.

With cumulative poisoning, the symptoms may include the tortoise showing signs of muscular weakness, the tortoise unable to lift itself to walk or unable to walk, and gastrointestinal upset including diarrhea.

Do not attempt to diagnose a case of poisoning yourself: specialist veterinary help should be sought as a matter of urgency.

If the poisoning is one that is cumulative, the tortoise should make a good recovery if the offending poison is removed, the tortoise is kept well hydrated and is fed on safe food so that the toxins can be eliminated from the liver and out of the body.

Prevention is always better than cure

  • Wash all store-bought products thoroughly, separating all leaves and removing any plastic or wire ties before offering to your tortoise.
  • When collecting leaves and flowers from plants growing in the wild not only wash thoroughly but also inspect carefully to ensure there are no leaves from plants and shrubs/trees which are toxic and that may have been collected inadvertently with the safe weeds you have collected.
  • Look at the condition of plants collected from hedgerows or verges before you pick them, and if they look to be withering or changing color from green to a yellowish/brown do not collect.  This may be a sign that the Council or local farmers have been spraying with weedkiller.  A simple phone call to the local Council will identify for you where and when spraying is being undertaken.
  • In your own garden ensure that plants or trees that are poisonous are not planted anywhere near your tortoise enclosure.
  • Do not use weed killers, pesticides or lawn fertilizers on areas that your tortoises will be exposed to.

Don’t FORGET!  Information provided in this article is not meant to be a substitute for expert medical advice.  If you suspect that your tortoise has had an adverse reaction to any food, or has ingested poison in any other way, then specialist veterinary advice should be sought immediately.
