With over 24,000 species of plants native to Australia, it’s no surprise we’re a nation of greenery-lovers. Things may look rosy for those with green thumbs, but not so for animals who discover common plants that are toxic to pets.

With the pandemic keeping people (and pets) mostly inside their homes, house plants – or gardens, if you’re lucky – became a much-needed link to the wide outdoors for many. And the love doesn’t appear to be backing off… Best plant that herb garden again before the harsher winter temperatures start rolling in.

What common plants are toxic to pets?

Before you shop for your next Pinterest-worthy plant, take a moment to check out something really important: whether your favourite plant could be toxic to pets. Some plants that have no harmful effects on humans, or are even eaten on purpose, can be deadly to the furry family members.

Here are some of the most common ones.

Fiddle Leaf Fig (Ficus Lyrata)

The Fiddle Leaf Fig is the social media star of the plant world. So much so that the New York Times called it the “it” plant of the design world. This plant can grow to a whopping 12 metres high, assuming you have a really, really tall house.

It’s undoubtedly beautiful, boasting fiddle-shaped leaves and a vibrant green colour. Unfortunately, it’s one of those plants that are toxic to pets. So no matter how Manhattan it looks in your place, it’s best to remove it.

Toxicity signs to look out for in your pet are:

  • Vomiting
  • Gastrointestinal irritation like diarrhea
  • Oral irritation
  • Skin irritation

What to do when your pet eats toxic plants

Ingesting a toxic plant won’t necessarily be deadly for your pet, but it can be. It’s crucial that you act quickly. As your pet metabolises the toxin, their condition can worsen very quickly.

What to do:

  • Stay calm
  • Call your vet’s emergency number. If you can’t get through, go to the vet in person
  • Take a sample or photo of the plant to show the vet
  • Make a note of any symptoms and the timeframe in which they’ve developed

What not to do when your pet eats toxic plants

If you think or know your pet has come into contact with a toxic plant, here’s what not to do:

  • Don’t induce vomiting unless instructed by the vet
  • Don’t put off a trip to the vet to “see how they are” as toxicity cases can deteriorate quickly

If you act quickly, decisively, and calmly, your pet has a much better chance of making a full recovery.
