Is English Hawthorn Toxic to Cats?

Cats are curious creatures. They love exploring their surroundings and sometimes they end up eating plants that are not safe for them. As a cat owner, you may be wondering if English Hawthorn is safe for your furry friend.

What is English Hawthorn?

English Hawthorn, also known as Crataegus laevigata or Crataegus monogyna, is a small, thorny tree or shrub that is native to Europe, North Africa, and Western Asia. It is popularly grown for its beautiful, fragrant flowers that bloom in late spring and its small, red fruits, also known as haws, that are edible and used in making jams, jellies, and other treats.

Is English Hawthorn Toxic to Cats?

English Hawthorn is not toxic to cats, according to the American Society for the Prevention of Cruelty to Animals (ASPCA). This means that if your cat eats the leaves, flowers, or fruits of the plant, it is unlikely to cause any serious harm to your pet.

However, ingesting any plant material can cause a mild upset stomach or diarrhea in cats and other animals. So, if your cat eats a significant amount of English Hawthorn, it may experience digestive problems.

The Benefits of English Hawthorn

While English Hawthorn is not toxic to cats, it actually has some benefits for both humans and animals. The plant has been used for centuries in traditional medicine to treat various health conditions such as:

  • Heart disease and high blood pressure
  • Chest pain and angina
  • Digestive problems
  • Anxiety and nervousness

Being rich in antioxidants, flavonoids, and other beneficial compounds, English Hawthorn may help improve the overall health and well-being of your cat, as well as prevent certain health problems.

Other Toxic Plants for Cats

While English Hawthorn is safe for cats, there are many other plants that are toxic and can cause serious harm to your pet. Some of the most common ones include:

  • Lilies - can cause kidney failure
  • Chrysanthemums - can cause vomiting, diarrhea, and skin rashes
  • Poinsettias - can cause vomiting, diarrhea, and mild irritation to the mouth and skin
  • Wisteria - can cause vomiting, diarrhea, and dehydration

It is important to keep these plants out of your cat's reach and to seek veterinary help immediately if you suspect your cat has ingested any toxic plants.

In Conclusion

English Hawthorn is not toxic to cats and can actually have some health benefits for them. However, like any plant, it can cause digestive problems if eaten in large quantities. As a responsible cat owner, make sure to keep your home and garden free of toxic plants and to provide your furry friend with a safe and healthy environment.
