Why are sunflowers dangerous to cats?

Eating sunflowers could result in digestive upset for your cat, but in most cases this symptom will ease on its own. The bigger concern is your cat consuming sunflower seed shells. These rough shells could irritate the digestive tract and even result in a blockage that may require surgery to remove.

What should I do if my cat has eaten sunflowers?

Keep an eye on your cat if they’ve ingested sunflowers but don’t rush to the vet. Cats have difficulty digesting raw plant materials, so your cat may experience vomiting or diarrhea. Unless you notice severe side effects, your cat will likely be just fine once their stomach upset passes.

Diagnosing plant poisoning in cats

If you think your cat has eaten a hazardous plant, visit your vet or an emergency vet clinic immediately. Bring a sample of the plant with you so the vet knows exactly what your cat consumed and be prepared to list any symptoms. Your vet will then recommend a treatment plan, which may involve inducing vomiting.

Symptoms of plant poisoning in cats

While sunflowers may be non-toxic to cats, other plants could cause poisoning. Look out for these symptoms if you think your cat may have ingested a hazardous plant:

Loss of appetite
Vomiting
Diarrhea
Drooling
Tremors or seizures
Difficulty breathing
Weight loss

Treatment

The treatment plan for a cat suffering from plant poisoning will depend on their specific symptoms and how severe those symptoms are. Some plants are only mildly toxic to cats, while others can cause serious health issues if not treated immediately. In most cases, sunflower ingestion will only give your cat an upset stomach, which will usually go away on its own.

How to prevent plant poisoning

Place any hazardous plants outside of the house in a garden or in a room with a door that can be closed. Make sure your garden area outside is blocked off from your cat or, better yet, don’t allow your cat outdoors unsupervised. You can also keep plants on a high shelf, as long as your cat is unable to reach it.

Are all parts of sunflowers safe for cats?

All parts of sunflowers are safe and non-toxic for cats to consume. However, the seeds could be a choking hazard, since cats don’t chew their food well.

How do I stop my cat from eating sunflowers?

The best way to prevent your cat from eating sunflowers — or anything you don’t want them to eat — is to keep the plant out of their reach. Place sunflowers in a room with a door you can close or in an area of the home your cat can’t access.

The bottom line: Are sunflowers poisonous for my cat?

All parts of a sunflower are non-toxic to cats, even the seeds, but if your cat ingests too much of the plant, they could end up with an upset stomach. And while sunflower seeds aren’t poisonous to cats, their small size could present a choking hazard.
