Lily of the Palace

Lily of the Palace

  • Alternative Names: Amaryllis, Fire Lily, Barbados Lily, Ridderstjerne

It has a broad, straight trunk and a thin, scraggly top as it becomes older. The dark blue-green compound leaves of the locust, with a lighter underside, add to the tree’s splendor and make it look lovely in the wind.

It has been found that locusts contain toxalbumins such as phasin, robin, and robitin. These substances are mostly contained in the locust’s bark, leaves, and seeds. When a part of a locust is ingested by felines, poisoning symptoms such as vomiting, depression, anorexia, weakness, difficulty breathing, bloody diarrhea, and death, may occur.

Milfoil

Milfoil

  • Alternative Names: Yarrow
  • Scientific Name: Achillea millefolium
  • Family: Asteraceae

Milfoil is a blooming plant that grows naturally in Northern Asia, Europe, and North America. Achillea millefolium is its scientific name.

The genus Achilles is named after Achilles, the Greek hero of the Trojan War and the finest warrior in Homer’s Iliad, who is claimed to have brought milfoil or yarrow with his army to treat battle wounds.

Milfoil contains poisonous components such as glycoalkaloids, monoterpenes, and sesquiterpene lactones. Milfoil poisoning is rare because the plant’s tannins give it a bitter taste that keeps animals from eating too much of it. Furthermore, to be killed, a cat would have to swallow an almost unimaginably massive amount of the plant. Milfoil toxicity in cats is characterized by vomiting, diarrhea, depression, anorexia, and hypersalivation.

During the day, the blooms open and close as the sun goes down.

The poisonous components found in moss roses are soluble calcium oxalates. The amount of oxalis taken, as well as the cat’s overall health, influence the severity of moss rose poisoning symptoms. Cats with chronic renal disease are at a higher risk. Kidney failure, tremors, and salivation are some of the symptoms that cats may experience after swallowing a piece of moss rose.

 

Mother of Millions

Chandelier plant

  • Alternative Names: Mother-In-Law-Plant, Kalanchoe, Devils Backbone, Chandelier Plant

Plantlets only grow at the end of the leaf, at the tip, on these leaves. Several stalks of Mother of Millions grow from the same plant. They tend to grow upwards, but they can also produce bushy areas.

Bufodienolides are the toxic components found in the mother of millions. Symptoms such as vomiting, diarrhea, and abnormal heart rhythm may appear in cats if they ingest a portion of mother of millions.

 

Mother-in-Law

Ceriman

  • Alternative Names: Hurricane Plant, Swiss Cheese Plant, Ceriman, Split-leaf Philodendron
  • Scientific Name: Monstera deliciosa
  • Family: Araceae

The mother-in-law is a popular houseplant. Its colorful leaves are lobed with elongated holes running the length of the blade. This is a feature that develops in young leaves throughout time. Because this plant can grow rather large, strong support is required to keep the stems from breaking. In most interior environments, it does not produce flowers or fruits.

The Mother-in-Law, like the other plants in the Araceae family, produces insoluble calcium oxides known as raphides. When these raphides are swallowed, they cause a severe burning sensation in the mouth and can even cause severe throat inflammation, causing the cat to suffocate. After the oxalate crystals are metabolized, they will congregate in the cat’s kidneys, transforming into a solid and eventually causing kidney damage or death. Cats commonly exhibit Mother-In-Law poisoning symptoms such as vomiting, hypersalivation, and oral irritation.

 

Mother-in-Law Plant

Chandelier plant

  • Alternative Names: Mother of Millions, Kalanchoe, Devils Backbone, Chandelier Plant
  • Scientific Name: Kalanchoe tubiflora
  • Family: Crassulaceae

The mother-in-law plant, also known as the chandelier plant, is a robust, completely bare, biennial, or more or less perennial, succulent plant that grows to heights of 0.2 to 2 meters. The stems of the upright plants are simple and round. When spread out, the three-seated, seemingly opposite, or alternate leaves are usually upright to straight.

Mother-in-Law plant or chandelier plant is considered toxic to dogs, cats, and horses, according to ASPCA Animal Poison Control Center as it contains bufodienolides. Vomiting, diarrhea, and abnormal heart rhythm are the common clinical signs that cats may show when they eat a portion of the mother-in-law plant.

Mother-in-Law’s Tongue

Golden Bird's Nest

  • Alternative Names: Snake Plant, Golden Bird’s Nest
  • Scientific Name: Sansevieria trifasciata
  • Family: Agavaceae

The mother-in-law’s tongue is a flowering species grown for its slick sword-like long leaves. Because of its low and high sunlight tolerance and ease of watering, this is a slow-growing plant that anyone can grow. Once this species matures, small greenish-white flowers may appear. Maintaining the proper conditions increases the plant’s chances of producing buds and then flowers.

Saponins are the main cause of toxicity of the mother-in-law’s tongue. If a part of the mother-in-law’s tongue is ingested by cats, it may cause them to experience symptoms such as nausea, vomiting, and diarrhea.

 

Mum

Mum plants are found to contain sesquiterpene, lactones, pyrethrins, and other potential irritants. Some animals, particularly cats, can be harmed by these substances. Mum plant toxicity in cats can cause vomiting, diarrhea, hypersalivation, incoordination, and dermatitis in cats.

 

Naked Lady

  • Alternative Names: Amaryllis Belladonna
  • Scientific Name: Amaryllis spp.

Over time, the large, rounded brown bulbs produce smaller bulbs, forming a large clump of plants. Old bulbs can grow up to be the size of a grapefruit.

The toxic properties of naked ladies include lycorine and other alkaloids. Because the symptoms of naked lady poisoning usually appear immediately, cats are less likely to consume large amounts of it. Naked lady poisoning symptoms can range from mild to severe. To be safe, consult a doctor right away if your cat consumes any portion of a naked lady. Vomiting, depression, diarrhea, abdominal pain, hypersalivation, anorexia, and tremors are the typical symptoms that cats may feel due to naked lady toxicity.

Similar to other members of the Amaryllidaceae plant family, Narcissus also contains substances such as lycorine and other alkaloids which are toxic to cats. Vomiting, salvation, and diarrhea are the common symptoms that may occur in cats after ingesting a part of narcissus. Large ingestions of narcissus may cause convulsions, low blood pressure, tremors, and cardiac arrhythmias.

 

Nasturtium

Nasturium

  • Alternative Names: Watercress, Brunnenkress

  • Thank you for compiling the list of toxic plants for cats. It is much appreciated! I am going to print it out and keep it in my purse so that I can consult it if I am ever in doubt about whether or not a plant is safe for my cat. I have a beautiful garden, and I want to make sure that my cat can enjoy it as much as possible, without running the risk of her getting sick.

    I also want to thank you for including pictures of the plants. This will be very helpful, since I am not necessarily familiar with all of them. Besides, you might be interested in this. It is great to have a handy reference like this, especially when I am out and about.

    Again, thank you so much for putting this together!
