Is Cliff Brake Toxic to Cats?

As a cat owner, we always strive to provide the best environment for our feline friends. That includes keeping our home clean and safe for them. Cats are curious creatures, and they often explore their surroundings with their mouths. That's why it's essential to be mindful of what plants and substances they can come into contact with, especially if you have indoor plants in your home.

One of the common plants that can grow in rock gardens, cliffs, and soil banks is Cliff Brake, a fern that belongs to the Pteridaceae family. This plant is often used by gardeners in landscaping, and some even bring it indoors. That begs the question, is Cliff Brake toxic to cats?

What is Cliff Brake?

Cliff Brake is a small, evergreen fern that usually grows in rocky areas, such as cliffs, hillsides, and slopes. It consists of two groups: the rock-loving, cliff plants have thick and leathery leaves, while upland ferns have delicate leaves that grow in soil banks. The fern has a unique shape, with fronds that resemble a bird's feather and range from light to dark-green color. Cliff Brake is not just common in the United States, but it can also be found in Europe, Asia, and Africa.

Is Cliff Brake Toxic to Cats?

According to the American Society for the Prevention of Cruelty to Animals (ASPCA), Cliff Brake is non-toxic to cats and dogs. It's also not listed as a toxic plant on the Pet Poison Helpline, which is a 24-hour animal poison control service available throughout North America.

However, it's important to remember that even non-toxic plants can still cause mild gastrointestinal distress in cats when ingested. The effects can range from vomiting and diarrhea to lethargy and loss of appetite. So, while Cliff Brake may not be toxic to your cat, it's still a good idea to monitor their behavior closely if you have indoor plants or gardens that they can access.

What Plants are Toxic to Cats?

If you're an avid gardener or have indoor plants, it's essential to be aware of the plants that can be toxic to cats. Here are some of the common plants that are hazardous:

  • Lilies: These are beautiful flowers that you should avoid having in your home if you have cats. They're toxic to cats and can cause kidney failure if ingested.
  • Poinsettias: While not as toxic as other plants, poinsettias can still cause gastrointestinal distress if ingested by your feline friend.
  • Autumn Crocus: This plant can cause vomiting, diarrhea, and even liver and kidney damage.
  • Azaleas and Rhododendrons: These non-native plants are toxic to both cats and dogs, with symptoms that include vomiting, drooling, and diarrhea. They can also cause heart problems if ingested in large amounts.

What are the Symptoms of Poisoning in Cats?

If you suspect that your cat has ingested a toxic plant, look out for these symptoms:

  • Loss of appetite
  • Vomiting
  • Diarrhea
  • Lethargy
  • Difficulty breathing
  • Irregular heartbeat
  • Abdominal pain or swelling
  • Seizures

If you notice any of these symptoms, seek immediate veterinary care as they can be life-threatening if left untreated.

Conclusion

In conclusion, Cliff Brake is not toxic to cats, but it's still essential to monitor your cat closely if you have indoor plants or gardens that they can access. Remember to keep toxic plants out of their reach and to seek veterinary care immediately if you suspect your cat has ingested a poisonous plant.
