Many common backyard and indoor plants are poisonous to pets, with ingestion resulting in a range of symptoms from gastrointestinal upsets to seizures or even death.
Our vets have listed 20 common household plants that are poisonous to dogs and cats, ways to prevent your pet from destroying your garden and pet friendly plants for you to enjoy! Keep your pet safe this summer!
Our pets are naturally curious and are known for getting into all sorts of mischief! Owning a pet can be a big responsibility and keeping them safe is an important part of pet ownership, with some dangers more obvious than others.
WARNING: If you believe your pet has consumed or has been in contact with a toxic plant please immediately contact your local vet, 24hr vet emergency centre or call the Australian Animal Poisons Helpline on 1300 TOX PET (1300 689 738). Delaying treatment may worsen the symptoms.

Is snake plant toxic to dogs and cats?
Yes. The Snake Plant, also known as Mother-in-Law's Tongue (Sansevieria trifasciata), is a hugely popular indoor plant thanks to how easily it grows in low light, but its long upright leaves contain saponins that make it toxic to both dogs and cats.
What happens if my pet eats snake plant? Saponins irritate the mouth and gut, so the main things to watch for are drooling, vomiting, diarrhoea and nausea. In practice, our vets most commonly see mild drooling and vomiting from snake plant chewing, rather than anything more serious, but it's still worth a call to the poisons helpline. Most cases are mild and settle on their own, but ingestion should always be taken seriously, especially in small dogs, cats and puppies.
A pet-friendly alternative: if you love the tall, architectural look of a Snake Plant, Calathea is a great low-light, pet-friendly swap that gives you a similar lush indoor feel without the risk to a curious cat or dog.
Is jasmine toxic to cats and dogs?
No. Star Jasmine (Trachelospermum jasminoides), the climbing variety most Australians mean when they say "jasmine" and the most-searched of the jasmine family, is non-toxic to dogs, cats and horses. If your pet has a nibble on the leaves or flowers of your courtyard climber, it's not cause for panic.
Why do so many pet owners worry about jasmine, then? The confusion usually comes down to a couple of toxic lookalikes that also get called "jasmine" in everyday speech. Night-blooming Jasmine (Cestrum nocturnum), sometimes sold as Lady of the Night, is a different plant altogether and is toxic to pets, potentially causing death. Carolina Jessamine (Gelsemium sempervirens) is another jasmine impostor and is genuinely dangerous, causing weakness, tremors and breathing difficulty if eaten.
The bottom line: if you're certain what's growing on your fence is genuine Star Jasmine, it's one of the safer climbers you can plant. If you're not sure, or you've got Night-blooming Jasmine or Carolina Jessamine instead, it's worth checking with your local nursery, since those genuinely warrant caution.
How do I stop my dog or cat from eating plants?
While removing all potentially toxic plants from your house and garden is the safest options when it comes to pets, this is not always possible. For pet owners who are renting or live in an apartment, removing plants from the garden is often not allowed. In these cases, keeping your pet separate from any harmful plants may be the best option.
1. Create barriers
Dogs: Consider fencing off areas of the garden which you do not want to give your pet access to.
Puppies are particularly mischievous and tend to get into many things that adult dogs don't even bother about. If you have a puppy consider keeping your puppy in a crate, playpen or gated room, safe from any potential risks when you are not home or are unable to monitor them. Our puppy-proofing checklist covers this in more detail.
If you are worried about what your dog gets up to during the day when you are not home, consider setting up a Pet Camera. Connecting to your home's WiFi network, monitor live video of your pet on your phone any time during the day to ensure they are safe and staying out of trouble.
Cats: Keeping them indoors will keep them safe from wandering and protect them from any potentially toxic outdoor plants. Our kitten-proofing guide has more tips if you've just brought a new cat home.
A safe way to exercise your cat outdoors is by walking them on a harness and lead or consider a longer adventure in a pet backpack.
2. Use a deterrent
For areas that are difficult to fence, try using a repellent spray or a chew deterrent spray such as Tropiclean Stayaway Spray, which can even be used on plants.
Water can be a great deterrent in the garden for pets that do not enjoy getting wet. Try setting up a timed sprinkler to spray on the area of the garden that you do not want your pet accessing. Not only will this keep water-hating pets out, but it will ensure that your garden stays well watered!
3. Provide environmental enrichment
A bored pet is a mischievous pet!! If you pet has nothing to do, they are more likely to get into things like your garden and chew on plants, dig holes and generally just get up to no good!
Dogs: Keep your dog busy by providing them with a range of Interactive Toys or Long Lasting Treats. This is a great way to exercise their body while stimulating their mind, and prevent problem behaviours.
Durable rubber chew toys satisfy your dogs natural urge to chew while keeping them occupied. The addition of a lickable paste treat and dogs can spend hours trying to clean up every last morsel. Try freezing in summer for a longer-lasting treat.
Cats: Keep your cat busy with a selection of interactive toys, to exercise their body and mind. Lick mats are designed to keep pets stimulated and entertained, reduce boredom and anxiety, as well as slow those that eat too quickly. Lick Mats can be loaded with pastes such as creamy treats or wet food for a long lasting treat.
Cats love to go vertical. Providing your cat with a selection of scratchers and cat trees to allows them to explore and exercise their natural climbing instincts.
Some cats enjoy grazing on grass from time to time and it provides them with a important source of environmental enrichment. Providing your indoor cat with fresh cat grass or cat nip is a great way to fulfil this natural instinct.
