Houseplants make a home feel cozy, but for pets some of them pose a real danger.
Over the years of practice, we have repeatedly seen situations where a cat or dog "just chewed a leaf" — and only a couple of hours later the owners were already on their way to the clinic with vomiting, swelling of the mouth, or severe weakness.
Below are 10 houseplants that most often cause problems for cats and dogs.
1) Anthurium
Why is it dangerous?
Contains calcium oxalate crystals, which irritate the mucous membranes and cause severe discomfort in the mouth.
Signs:
Drooling, oral pain, refusal to eat, swelling of the lips and tongue, vomiting.
What to do?
Remove the plant from access. Gently rinse the mouth with water. If there is swelling, vomiting, or refusal to eat — go to the clinic.
2) Dieffenbachia
Why is it dangerous?
One of the leaders in "household poisonings", especially in cats. It can cause irritation and chemical burns of the mucous membranes.
Signs:
Sudden drooling, obvious pain (the animal may become restless, "rub its face"), swelling, sometimes difficulty breathing.
What to do?
Do not delay. If there is swelling or breathing is difficult — seek veterinary care immediately.
3) Lilies
Why are they dangerous?
Extremely dangerous for cats. Even pollen or water from the vase can lead to acute kidney failure.
Signs:
Lethargy, refusal to eat, vomiting, intense thirst, changes in urination (too frequent or almost absent).
What to do?
Emergency veterinary care. Time is critical.
4) Ficus
Why is it dangerous?
The milky sap irritates the gastrointestinal tract and skin. In sensitive animals, symptoms can be quite pronounced.
Signs:
Vomiting, diarrhea, itching, redness of the mucous membranes, sometimes drooling.
What to do?
Eliminate contact with the plant. If symptoms persist or worsen — a veterinary examination is required.
5) Monstera
Why is it dangerous?
Contains calcium oxalates, like many other popular decorative plants.
Signs:
Irritation of the mouth, drooling, vomiting, refusal of food.
What to do?
Restrict access. If symptoms are pronounced — go to the clinic.
6) Philodendron
Why is it dangerous?
Similar in toxicity to monstera and dieffenbachia — irritates the mucous membranes.
Signs:
Drooling, swelling of the mouth, vomiting, apathy.
What to do?
Remove the plant. If there is swelling, vomiting, or lethargy — consult a veterinarian.
7) Azalea
Why is it dangerous?
Contains toxins that can affect the heart and nervous system.
Signs:
Severe vomiting, diarrhea, weakness, unsteady gait, sometimes seizures.
What to do?
Urgently go to the clinic. This plant is considered potentially fatal.
8) Caladium
Why is it dangerous?
Causes severe irritation of the mucous membranes, often quickly leading to drooling and swelling.
Signs:
Drooling, swelling of the tongue, pain, refusal to eat.
What to do?
Remove the plant from access. If swelling or the general condition worsens — see a veterinarian.
9) Zamioculcas
Why is it dangerous?
Moderately toxic, but in cats it often causes noticeable gastrointestinal problems.
Signs:
Vomiting, diarrhea, decreased appetite, lethargy.
What to do?
If contact is confirmed — monitor closely. If vomiting, diarrhea, or refusal to eat occurs — consult a veterinarian.
10) Oleander
Why is it dangerous?
One of the most dangerous houseplants: its toxins affect the heart.
Owners sometimes try to "treat at home", but this is exactly the case when experiments should be avoided.
What to do immediately:
Remove plant remnants and prevent further ingestion.
If possible, take a photo of the plant and estimate how much was eaten.
Do not give medications "at random".
When to seek help urgently:
If any symptoms appear — vomiting, drooling, lethargy, swelling, tremors, unsteady movement — contact a veterinary clinic.
Most of these cases start with curiosity: the pet sniffed, licked, or chewed. Prevention is simple — keep dangerous plants out of reach or replace them with safe alternatives.
If you are unsure whether a plant in your home is safe, contact us — it is much easier to check in advance than to urgently treat the consequences later.
