We all love our pets and want what it best for them. Keeping them safe can be a big responsibility and dangers to our pets are not always obvious. With owners spending more time at home than ever before, there has been an influx in home renovations and improvements. Plants, both indoor and outdoor have become popular decorations in Australian homes.

While a little extra foliage can make a lovely addition to homes, not all greenery is safe for pets, with some varieties causing serious illness or even death. Here is a list of the most common toxic plants that may pose a risk to your pet plus some pet-friendly options that are worry-free.

Is a poisonous plant lurking in your backyard?

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.

Common Household Plants Toxic to Pets

Lilies

It is a little known fact that cats and lilies do not mix. Lilies are commonly found in gardens, flower arrangements and indoor plants with those of the Daylily (Hermerocallis) or True Lily (Lilium) families the most dangerous. The consumption of any part of the plant, including the leaves, stem, flower, pollen or even the water from a vase can result in fatal kidney failure. If you have a cat at home it is best to avoid lilies completely!. Lilies are very common in flower arrangements, so if you are giving a gift to a friend with cats, ensure it does not contain lilies!.

Yesterday, Today and Tomorrow

The Yesterday, Today and Tomorrow (Brunfelsia) is incredible dangerous to pets. All parts of the plant are highly toxic if ingested containing two different toxins, brunfelsamidine and hopeanine. The berries which seem to be highly palatable to dogs are especially toxic. Clinical signs after ingestion include uncontrollable seizures lasting days, tremors, vomiting, diarrhoea and incoordination.

Don't let these pretty flowers fool you, the Oleander (Nerium oleander) is extremely toxic to all animals when consumed. Clinical signs can quickly develop and include vomiting. diarrhoea, heart abnormalities and neurological signs.

Aloe Vera

Commonly grown in backyards around Australia, Aloe Vera is known for its medicinal properties with the sap or gel a common ingredient in many beauty and medicinal products. The Aloe Vera plant contains saponins and anthraquinones, which when ingested can cause vomiting and diarrhoea.

Many pets enjoy eating fresh grass. If you have an indoor cat you may want to consider the addition of a Catit Grass Planter so they can graze on grass at their leisure!

Azalea

Azaleas are a species of Rhododendron and are a pretty addition to many gardens along the east coast of Australia. These plants contain grayanotoxins which when ingested can cause vomiting, diarrhoea, weakness and cardiac abnormalities.

Snake Plant
