Is Moss Poisonous To Cats? A Guide For Cat Owners

Moss is a small, non-vascular plant that grows in damp and shady places. There are thousands of different species of moss, some of which are beneficial and some of which are harmful to cats. 

Cats may be curious about moss and try to nibble on it or use it as a source of hydration or nutrients. But is moss poisonous to cats? The answer is not straightforward, as it depends on the type and amount of moss ingested, as well as the cat’s health and sensitivity.

In this article, we will explore the potential dangers of moss poisoning in cats, how to identify and treat it, and how to prevent it from happening.

The Dangers of Moss Poisoning in Cats

Moss poisoning in cats can cause a variety of symptoms, depending on the species and quantity of moss consumed. Some of the most common problems associated with moss poisoning in cats are:

Gastrointestinal issues

Moss can irritate the cat’s stomach and intestines, causing vomiting, diarrhea, loss of appetite, and abdominal pain. Some mosses may also contain parasites, bacteria, or fungi that can infect the cat’s digestive system and cause further complications.

Thiaminase deficiency

Some mosses, such as Java moss and Christmas moss, contain an enzyme called thiaminase, which breaks down thiamine (vitamin B1) in the cat’s body. 

Both the nervous system’s normal operation and the metabolism of carbohydrates depend on thiamine. A lack of thiamine can lead to neurological disorders, such as seizures, tremors, weakness, and confusion.

Allergies

Some cats may be allergic to moss or its spores, which can trigger an immune response in the cat’s body. This can result in skin rashes, itching, swelling, sneezing, coughing, and difficulty breathing. 

In severe cases, anaphylaxis may occur, which is a life-threatening condition that requires immediate medical attention.

Blockages

Moss can also pose a physical hazard to the cat’s body, as it can get stuck in the cat’s mouth, throat, or intestines, causing obstruction and choking. 

This can prevent the cat from breathing or eating normally and may require surgery to remove the blockage.

Examples of Toxic and Non-Toxic Moss Species

Not all mosses are equally toxic to cats. Some mosses are harmless or even beneficial, while others are highly poisonous and can cause serious harm. Here are some examples of toxic and non-toxic moss species, according to the ASPCA and PetMD:

Toxic mosses

These mosses should be avoided by cats, as they can cause severe symptoms or even death. Some examples are:

• Sphagnum moss: This moss is commonly used as a soil conditioner or a decorative element in gardens and terrariums. However, it can cause gastrointestinal irritation, thiaminase deficiency, and liver damage in cats.

• Club moss: This moss is also known as ground pine or running cedar, and it resembles a miniature evergreen tree. It contains alkaloids that can cause vomiting, diarrhea, low blood pressure, and respiratory depression in cats.

• Irish moss: This moss is also known as carrageenan moss or sea moss, and it is often used as a thickening agent in food and cosmetics. It can cause gastrointestinal upset, allergic reactions, and kidney problems in cats.

Non-toxic mosses

These mosses are generally safe for cats, as they do not contain any harmful substances or enzymes. Some examples are:

• Sheet moss: This moss is also known as hypnum moss or carpet moss, and it forms a dense mat of green foliage. It is often used as a ground cover or a lawn alternative. It does not pose any threat to cats unless they eat too much of it and cause a blockage.

• Reindeer moss: This moss is also known as caribou moss or lichen, and it grows in arctic and alpine regions. It is a source of food for reindeer and other animals, and it has antiseptic and anti-inflammatory properties. It is safe for cats to consume, as long as it is not contaminated with pollutants or pesticides.

• Spanish moss: This moss is also known as tillandsia or air plant, and it hangs from trees and branches. It is often used as a decorative element or a nesting material for birds. It is harmless to cats unless they are allergic to it or it contains insects or parasites.

How to Diagnose and Treat Moss Poisoning in Cats

If you suspect that your cat has eaten moss, you should monitor its behavior and look for any signs of poisoning, such as:

– Vomiting

– Diarrhea

– Loss of appetite

– Abdominal pain

– Lethargy

– Drooling

– Difficulty breathing

– Seizures

– Tremors

– Weakness

– Confusion

If you notice any of these symptoms, you should take your cat to the veterinarian as soon as possible, as moss poisoning can be fatal if left untreated. 

The veterinarian will perform a physical examination and run some tests, such as blood work, urine analysis, and X-rays, to determine the type and severity of the poisoning. The treatment will depend on the specific case, but it may include:

• Inducing vomiting: This may help to expel some of the moss from the cat’s stomach if done within an hour of ingestion. However, this should only be done under the guidance of a veterinarian, as some mosses may cause more harm if vomited.

• Activated charcoal: This may help to bind some of the toxins in the cat’s intestines and prevent them from being absorbed into the bloodstream. However, this should only be given by a veterinarian, as it may interfere with other medications or treatments.

• Fluid therapy: This may help to hydrate the cat and flush out some of the toxins from the cat’s kidneys and liver. It may also help to correct any electrolyte imbalances or acid-base disorders caused by the poisoning.

• Antihistamines: These may help to reduce the inflammation and itching caused by an allergic reaction to moss or its spores. They may also help to ease the respiratory distress caused by anaphylaxis.
• Anticonvulsants: These may help to control the seizures or tremors caused by thiamine deficiency or neurological damage. They may also help to calm the cat and prevent further injury.

• Antibiotics: These may help to treat any bacterial or fungal infections caused by moss or its parasites. They may also help to prevent any secondary infections that may arise from the poisoning.

• Surgery: This may be necessary to remove any blockages caused by moss in the cat’s mouth, throat, or intestines. It may also be required to repair any damage caused by the poisoning to the cat’s organs or tissues.
