Pets love houseplants, even if this love is not always mutual. Combining your favorite animals with house plants poisonous to dogs and cats in one apartment becomes a real challenge. Cats and dogs are prone to chew flowers and grass because of a lack of certain substances in the body or simple curiosity.
Sometimes, animals instinctively sense danger. But over the years of domestic living, they have lost the ability to recognize poisonous things. Unlike nontoxic houseplants for dogs and cats, eating or licking toxic plants can cause severe poisoning, allergies, and even death in cats, dogs, parrots, hamsters, etc.

Common Signs of Your Pet's Intoxication by Plants
If you have indoor plants poisonous to dogs or other pets, you must always keep an eye on the animal. If the pet behaves suspiciously, inspect the plants for signs of damage and bites on the leaves and stems. The following symptoms are a direct indication of poisoning. If any are found, the animal must be given first aid and urgently shown to the vet!
- Nausea
- Vomiting
- Drowsiness or overexcitement
- Weakness
- Twitching
- Diarrhea
- Drooling
- Irritation of the skin, gums, or eyes
First Aid for Poisoning
The most important thing is to remove the toxic particles of the plant from the skin, mucous membranes, or the animal's body as soon as possible. If the sap of plants poisonous to dogs gets on the skin or eyes, rinse them with plenty of water. If there is a suspicion that the animal has swallowed a piece of the plant, it is necessary to give a large amount of water, try to induce vomiting, and give sorbents.
The next step is to visit the vet. In such a situation, you cannot hesitate! You are risking your pet's life, and every minute matters. Bring a photo of the eaten plant with you so the vet can determine the type of toxin and prescribe adequate therapy. Usually, animals don't eat a lot of poisonous leaves, so the intoxication is rarely severe. Nonetheless, everything depends on your pet and its health condition.
How to Keep Pets Safe?
The first and obvious thing is to give up buying house plants poisonous to cats or dogs, even if they don't show interest in them — no pet is safe then. But if you have owned a toxic plant for some time and now have a pet, the second tip is to keep plants in separate rooms. For example, you may put the plant on a balcony or loggia and teach pets that green in a pot is dangerous. Or, you can at least put the pots on a high shelf where your pet won't reach them.
