Are Azaleas Poisonous to Cats? Keeping Your Cat Safe

Azaleas are shrubs that bloom beautiful flowers in the springtime. They make vibrant additions to any outdoor garden. However, they’re not the safest plant for cats.

Azaleas are toxic to both dogs and cats. So, if you have a rather curious cat, it’s important to be cautious with this plant. Here’s what you need to know about azaleas and how you can protect your cat from them.

What Makes Azaleas Poisonous To Cats?

Azaleas are also commonly known as Rosebays and Rhododendron, and they’re part of the Ericaceae family. They contain a toxin called, “grayanotoxin.” When ingested, this toxin starts to affect a cat’s sodium levels, which then has a negative impact on its heart and skeletal muscles.

All parts of the azalea are toxic to cats. If a cat ingests any part of the plant, it may start to exhibit some symptoms between 20 minutes to 2 hours later:

  • Abdominal pain
  • Abnormal heart rate or rhythm
  • Depression
  • Diarrhea
  • Disorientation
  • Hypersalivation
  • Lethargy
  • Loss of appetite

Depending on how much of the plant your cat ingested, it may display more severe symptoms:

  • Collapse
  • Coma
  • Seizures
  • Temporary blindness

What To Do if Your Cat Eats an Azalea

If your cat eats a part of an azalea, call your veterinarian right away. It’s often unclear to tell just how much your cat ate, so it’s best to play it safe and reach out to a professional.

Sometimes, veterinarians will administer activated charcoal, which can help prevent the body from absorbing the toxin. They can also administer a gastric lavage to empty out the stomach.

Depending on the severity of the poisoning, your cat may be monitored for 48 hours in a hospital to ensure that it’s in stable condition.

Keeping Your Cat Away From Azaleas

It’s best to have a garden free of azaleas, but if this hardy shrub has been planted for years, it’s difficult to just uproot it and clear it out of your garden.

So, if you have a particularly independent outdoor cat that seems to be getting too close to an azalea shrub, here are some things you can try to deter it.

Install a Fence

Sometimes, a little obstacle can diminish a cat’s curiosity. There are several short, decorative garden fences that you can stake around the plant to make it more difficult for your cat to reach it and dig around it.

Sprinkle Cayenne Pepper

Cats don’t like the smell of cayenne pepper, so you can sprinkle some around or on the leaves of the plant. Just make sure to be extra careful when using cayenne pepper. It usually comes as a fine powder and can get in your eyes and mouth pretty easily.

Lay Out Citrus Fruit

Cats also don’t like the smell of citrus, so you can try using oranges or lemons to keep them away from azaleas. Sometimes, it’s enough to just lay slices of fruit around the plant. If this doesn’t work, you can try spraying a diluted formula of water and lemon juice onto the leaves.

If you’re using a spray, make sure to test it out on a small section of the plant first. If the formula is too concentrated, it can end up damaging the plant.

Use Pet Repellent Spray

Some pet supply companies have their own cat repellent formula that you can spray to keep cats away. The formula is often very sour or very bitter, so when cats taste it, it leaves an extremely unpleasant taste in their mouths.

Most sprays are effective for about 24 hours, so you’d have to be diligent with spraying the plants. However, with some consistency, cats can learn to avoid the plant.

Final Thoughts on Cats and Azaleas

Azaleas are toxic to cats and can be harmful in varying degrees. It’s best to not have azaleas in your garden if you have cats around. However, if it’s unavoidable, there are several methods you can try to keep your cat away from them. You might have to try combining some methods to discourage a determined cat.

At the end of the day, your cat’s safety is most important. So, if your cat repeatedly goes near an azalea bush, it’s best to remove it to avoid any potentially fatal consequences.
