Sunflowers are a bright addition to any yard or garden, but do they present a danger to your cat? Unfortunately, some of the prettiest plants can be toxic or even deadly to felines, but sunflowers are a cat-safe delight. However, it’s a good idea to keep your cat from eating these plants, both for your garden’s beauty and your cat’s comfort.
Learn all about the potential dangers of plant poisoning and how sunflowers could upset your cat’s health.
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
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.
