Are Sunflowers Toxic to Cats? What You Need to Know!

We are all quite familiar with the grand and glorious sunflower! These incredible flowers are a welcome sight in many gardens found worldwide and can even be kept indoors as potted plants or cut flowers. However, is it safe to have them inside or in your garden when you have a cat?

The good news is that sunflowers are not toxic for cats. But your cat might experience some stomach issues if they nibble on them.

We’ll go into a little more detail about sunflowers and what might happen if your cat eats some of its leaves or petals.

A Little About the Sunflower

Sunflowers are grown naturally in North America and were cultivated initially by First Nations people for a wide variety of uses – medicinal, food, cosmetics, and the plant itself for building material.

You can find sunflowers all over North America as well as Europe – they are pretty much grown around the world.

They are heliotropic flowers, which means they follow the sun as it moves across the sky from the east to the west. Even at night, the flower repositions itself towards the east in time to meet the sun in the morning.

And, of course, other than their sunny beauty, sunflowers are famous for their seeds and oil. Both are known to be healthy additions to our diet.

Sunflowers and Cats

The ASPCA has sunflowers listed as non-toxic for cats as well as dogs and horses. This is good news if you have sunflowers in your garden or home! Essentially, if your cat nibbles on some petals or leaves, nothing terrible will happen.

Having said that, vets warn that some cats might end up with an upset stomach after eating sunflowers. Cats are obligate carnivores, which means that about 70% of their diet needs to be made up of meat, and plant matter is something they just don’t need.

Too much vegetation and plant matter in your cat’s diet can lead to digestive issues, including nausea, vomiting, and diarrhea. And obviously, the more sunflowers your cat eats, the worse the stomach issues will get.

How About Sunflower Seeds?

Most sunflower seeds tend to be salted, which is a huge no-no for cats. The Pet Poison Helpline considers salt to be toxic for cats, and it can lead to some of the following issues:

  • Decreased appetite
  • Vomiting
  • Diarrhea
  • Incoordination
  • Lethargy
  • Excessive urination and thirst
  • Coma
  • Tremors
  • Seizures

If your cat has eaten anything with extra salt and exhibits any or some of these symptoms, bring your cat to the veterinarian immediately.

You should also avoid the shells as they can be sharp and might prove dangerous for your cat in addition to the salt. So, if the sunflower seeds are unsalted and unseasoned and are without the shell, a few will be fine if your cat happens to eat some.

The good news is, most cats aren’t particularly interested in eating sunflower seeds, so it’s something you don’t generally have to worry about.

And Sunflower Oil?

Sunflower oil is usually pretty safe for cats, but only that it’s not toxic. However, excess oil, of course, means excess fat, which can lead to obesity for your cat. If your cat happens to lap up some sunflower oil, it’s absolutely fine.

It’s just something that you shouldn’t give to your cat on a regular basis. It’s unnecessary for a cat’s diet since the fat that cats need come from animal fat, not plants.

Other Flowers That Are Safe for Cats

If you’re wondering what other flowers are safe to be around your cat, you can bring any of these to your home:

While these flowers are all non-toxic for cats, just like with the sunflowers, there’s always the risk of some stomach upset if your cat ingests any. You just don’t have to worry about your cat being poisoned by these flowers.

Common Flowers You Should Keep Away From Cats

The following are all flowers considered quite toxic for cats and should always be kept away from them. Symptoms can range from serious stomach upset to kidney failure to death. We’ll just go over the 10 most toxic flowers for cats in alphabetical order.

  1. Autumn Crocus: The Autumn Crocus is very toxic and can lead to respiratory failure as well as kidney and liver damage. The Spring Crocus is also toxic and might lead to stomach upset.
  2. Azalea: Ingesting just a few leaves can cause vomiting, diarrhea, and drooling. Without vet help, the cat can lapse into a coma and potentially die.
  3. Cyclamen: The roots of this plant are the most dangerous part and can lead to severe vomiting and possibly death.
  4. Lilies: Not all lilies are deadly, as some just might make your cat feel a little sick or develop some irritation around the mouth. But the Tiger, Day, Easter, Japanese Show, and Asiatic lilies are all seriously dangerous. Only a couple of petals or leaves can cause acute kidney failure and possibly death. Even licking a lily plant or the pollen can cause poisoning.
  5. Oleander: Both the flowers and the leaves are very toxic and can cause severe vomiting, slow the heart rate, and lead to possible death.
  6. Daffodils: They can cause severe vomiting and possible cardiac arrhythmia as well as respiratory depression.
  7. Lily of the Valley: The symptoms can include diarrhea, vomiting, a drop in the heart rate, cardiac arrhythmia, and possible seizures.
  8. Sago Palm: The seeds and leaves of this palm can cause vomiting, bloody stools, acute liver failure, damage to the stomach lining, and possibly death.
  9. Tulips: The tulip bulb is the most poisonous part. Diarrhea, vomiting, excessive drooling, and irritation to the mouth and esophagus might occur.
  10. Hyacinths: The same kind of symptoms of toxicity can occur from the hyacinth as we see with the tulip.

The above list is not all the toxic flowers out there. Have a look at the Pet Poison Helpline for a more comprehensive list of poisonous flowers for cats.

If you believe your cat has touched or ingested any of these flowers (and this includes the petals, stems, leaves, and roots), take it to your vet immediately, and be sure to bring the plant with you for proper identification. This helps with the treatment.

Conclusion

So, if you’re at all worried about having sunflowers around your cat, you don’t need to be. The occasional small snack won’t hurt your cat, and the possibility of an upset stomach will usually be the only result.

While sunflowers are generally safe for cats, you certainly shouldn’t encourage your cat to eat them. As we discussed earlier, cats don’t need to eat vegetation as a part of their regular diet, and you won’t want to risk having a sick cat on your hands. But otherwise, go ahead and enjoy your sunflowers risk-free!
