Cats and Toxic Plants in Australia

Keep your pet safe from toxic plants and household poisons is the topic of our three-part blog series. If you have a dog, we recommend you check out part one ‘Dogs and Toxic Plants‘.  In part two, Kevin Crawshaw has researched into cats and toxic plants in Australia.  Kevin has done the hard work for us and put together a list of plants that can be toxic to cats with varying degrees of danger to their life and health.

Cats are more likely to remain close to their territory even if they are allowed to roam. However, there are still many plants that are potentially dangerous out there, so it’s well worth taking the time to check out the list below to see what can be found in Australia.

These plants on our list are commonly found in our suburban gardens and outdoor areas. Care should also be taken when choosing indoor plants as some of these can cause serious health effects to cats.  The list is a guide only and by no means fully comprehensive, so look at the resources below or talk to your veterinarian for more information.  If your cat shows any signs of illness including vomiting, drowsiness, diarrhoea or breathing difficulties, take your pet to the vet immediately.
