Can Cats Eat Aloe?

Aloe vera, often hailed as the “plant of immortality” by ancient civilizations, has long been revered for its myriad of health and beauty benefits. Wander through the aisles of any health store, and you’ll likely find aloe vera juices promising digestive relief or gels boasting skin-soothing properties. Its succulent leaves, packed with a gel-like substance, have been a staple in skincare routines, offering hydration and healing properties. Moreover, the rise of holistic health trends has seen many of us incorporating aloe vera into our diets, believing in its detoxifying and anti-inflammatory benefits.

But as we sip on our aloe-infused drinks or apply our aloe-rich creams, a common question lingers for pet owners: “If it’s beneficial for me, is it also safe for my furry friend?” After all, our pets are part of our families, and it’s only natural to want to share the best with them. But when it comes to aloe vera and cats, the answer might surprise you.

Curious to know more? Let’s delve into the world of aloe vera and discover whether this ancient plant is a friend or foe to our feline companions.\

What Is Aloe?

Aloe vera, a name that resonates with healing and rejuvenation, is not just a modern-day wonder plant; its roots trace back thousands of years. Originating from the Arabian Peninsula, this succulent plant has since spread across the world, adapting to various climates and terrains. Historical records, including ancient Egyptian papyrus scrolls, mention aloe vera as the “plant of eternity,” and it was widely used for its medicinal properties. Cleopatra herself was believed to have used aloe vera as part of her daily beauty regimen, valuing its moisturizing and anti-aging properties.

Over the centuries, aloe vera’s reputation as a healing plant has only grown. The thick, fleshy leaves of the aloe plant contain a clear gel, which is where most of its beneficial properties reside. This gel is composed of around 99% water, but the remaining 1% is a powerful synergy of nutrients, including vitamins, minerals, amino acids, and enzymes.

Today, aloe vera’s applications are vast and varied. In the realm of skincare, it’s celebrated for its moisturizing, anti-inflammatory, and wound-healing properties. From sunburn relief creams to daily moisturizers, aloe vera has become a cornerstone ingredient, cherished for its ability to soothe irritated skin and provide deep hydration. Beyond skincare, aloe vera has made its mark in the health and wellness industry. Supplements and juices made from aloe vera claim to aid digestion, boost the immune system, and even help regulate blood sugar levels.

However, as we embrace aloe vera’s benefits for ourselves, it’s essential to understand its effects on other members of our household, especially our pets. Before you consider sharing this wonder plant with your feline friend, let’s explore its relationship with cats in more depth.

Can Cats Eat Aloe Vera?

For many of us, our cats are not just pets; they’re family. Naturally, we want to share the best of everything with them, especially when we discover something beneficial for our health. But when it comes to aloe vera, a plant celebrated for its myriad of human benefits, the question arises: Is it safe for our feline friends?

Toxicity of Aloe Vera to Cats

The short and straightforward answer is no, cats should not eat aloe vera. While the inner gel of the aloe plant is where most of its beneficial properties for humans reside, it can contain compounds that are harmful to cats.

  1. Anthraquinones: Found in the latex, which is the yellowish substance just beneath the plant’s skin, anthraquinones act as a natural laxative. When ingested by cats, these compounds can cause gastrointestinal upset, leading to symptoms like vomiting and diarrhea.
  2. Saponins: These are soapy substances found throughout the aloe plant, including in the gel. Saponins can be toxic to cats and may lead to a range of symptoms from gastrointestinal upset to tremors and, in severe cases, even depression.

Symptoms of Aloe Vera Ingestion in Cats

If a cat consumes any part of the aloe vera plant, they might exhibit one or more of the following symptoms:

  • Vomiting
  • Diarrhea
  • Tremors or shaking
  • Anorexia (refusal to eat)
  • Change in urine color (may become reddish)

Immediate Action

If you suspect your cat has ingested aloe vera:

  • Remove any remaining plant material from their mouth.
  • Do not induce vomiting unless explicitly instructed by a veterinarian.
  • Contact your veterinarian or an emergency animal clinic immediately. They can provide guidance on the next steps and whether any specific treatments are necessary.

The Nutritional Components of Aloe Vera

Aloe vera is more than just a simple plant; it’s a nutritional powerhouse. Beneath its spiky exterior lies a reservoir of compounds that have made it a sought-after remedy for various ailments and a staple in many health and beauty products. Let’s delve into the rich tapestry of nutrients found in aloe vera and understand why it’s so revered.

1. Vitamins: Aloe vera is a source of several essential vitamins that play crucial roles in our health.

  • Vitamin A: Important for vision, immune function, and skin health.
  • Vitamin C: An antioxidant that aids in skin health, wound healing, and immune function.
  • Vitamin E: Another antioxidant that helps protect cells from damage and supports skin health.
  • B Vitamins (B1, B2, B6, and B12): Vital for energy production, brain function, and the formation of red blood cells.

2. Minerals: These are essential for various bodily functions, from bone health to nerve function.

  • Calcium: Crucial for bone health, muscle function, and nerve signaling.
  • Zinc: Supports immune function, wound healing, and DNA synthesis.
  • Magnesium: Important for muscle and nerve function, bone health, and energy production.
  • Potassium: Helps regulate blood pressure, fluid balance, and nerve and muscle function.
  • Chromium: Assists in carbohydrate, fat, and protein metabolism.

3. Enzymes: Aloe vera contains enzymes that can aid digestion and reduce inflammation.

  • Amylase: Breaks down carbohydrates into sugars.
  • Lipase: Helps digest fats.
  • Bradykinase: This enzyme helps reduce inflammation when applied topically.

4. Sugars:

  • Polysaccharides: These long-chain sugars, like acemannan, are believed to have anti-inflammatory and immune-boosting properties.

5. Amino Acids: Aloe vera gel contains 20 of the 22 essential amino acids required by the human body, which are the building blocks of proteins.

6. Fatty Acids: Aloe contains plant sterols with anti-inflammatory properties, such as campesterol, β-sisosterol, and lupeol.

Benefits for Humans: The myriad of compounds in aloe vera offers a range of benefits for human health and well-being:

  • Digestive Health: The enzymes and polysaccharides in aloe vera can help soothe the digestive tract, potentially aiding in conditions like acid reflux and irritable bowel syndrome.
  • Skin Health: Its anti-inflammatory and moisturizing properties make aloe vera a popular remedy for sunburns, minor cuts, and skin irritations.
  • Immune Support: The polysaccharides in aloe vera can stimulate white blood cells, bolstering the immune system.
  • Antioxidant Properties: Vitamins C and E, along with other compounds in aloe, help combat oxidative stress in the body.
  • Blood Sugar Regulation: Some studies suggest that aloe vera might help lower blood sugar levels in people with type 2 diabetes.

While aloe vera’s benefits for humans are well-documented, it’s essential to approach its use with caution, especially when considering our pets. As we’ll see, what’s beneficial for us might not always be safe for our feline companions.

Pros and Cons of Cats Eating Aloe

While the general consensus among veterinarians and pet experts is that aloe vera is not safe for cats, for the sake of a comprehensive overview, let’s explore both the potential pros and cons.


  1. Natural Laxative Properties: The anthraquinones in aloe vera have natural laxative effects. In theory, if a cat were suffering from constipation, aloe might help. However, this is a double-edged sword, as the same compounds can lead to severe diarrhea and dehydration.
  2. Anti-inflammatory Benefits: Aloe vera is known for its anti-inflammatory properties in humans. If these benefits were transferable to cats without the associated risks, it could potentially help with inflammation or skin irritations.


  1. Toxic Compounds: Aloe vera contains compounds like saponins and anthraquinones that are toxic to cats. These can lead to gastrointestinal upset, tremors, and other health issues.
  2. Gastrointestinal Distress: Even if a cat were to consume aloe vera for its laxative properties, the risk of severe diarrhea, vomiting, and dehydration is high.
  3. Potential for Anorexia: Cats that ingest aloe vera might experience a loss of appetite, which can lead to weight loss and other health complications if not addressed promptly.
  4. Change in Urine Color: Aloe vera ingestion can lead to a reddish discoloration in a cat’s urine, which can be alarming for pet owners.
  5. Risk of Chemical Ingestion: Many aloe vera products, especially those designed for human use, contain added chemicals, preservatives, and flavorings. These can be harmful or even deadly to cats.

While there might be a couple of theoretical benefits to cats consuming aloe vera, the cons significantly outweigh the pros. The potential risks associated with aloe vera ingestion make it a substance best kept away from our feline friends. Always prioritize your cat’s safety and consult with a veterinarian before introducing any new substance or plant into their environment.

Safe Alternatives to Aloe Vera for Cats

When it comes to our feline friends, ensuring their safety is paramount. While aloe vera might be off the table, there are several other plants and herbs that are not only safe for cats but can also offer them various benefits.

Catnip (Nepeta cataria)

is perhaps the most famous herb among cat owners. This plant can induce a euphoric reaction in many cats, leading to playful behaviors and increased activity. Beyond its entertainment value, catnip can also serve as a mild sedative when consumed, helping to calm anxious or stressed cats.

Catmint (Nepeta mussinii)

A relative of catnip, is another herb that cats might find attractive. While it doesn’t induce the same intense reactions as catnip, it can still be a delightful treat for your feline friend and has a similar calming effect when ingested.

Valerian root

Known for its sedative properties in humans, and it can have a similar effect on cats. Some cats are attracted to valerian in the same way they are to catnip, and it can be used as a calming agent in stressful situations.


Another herb that’s safe for cats and has calming properties. It can help soothe an upset stomach and reduce anxiety. However, always ensure that any chamomile products you offer your cat don’t contain any added essential oils or flavorings.


A safe plant that many cats enjoy nibbling on. It’s packed with nutrients and can aid in digestion. Plus, it can serve as a safer alternative for cats that have a tendency to chew on houseplants.


Not only a common culinary herb but also safe for cats in moderation. It can freshen a cat’s breath and provide them with some additional vitamins and minerals.

Incorporating these plants and herbs into your cat’s environment or diet can offer them both entertainment and health benefits. However, always introduce any new plant or herb gradually and monitor your cat for any adverse reactions. And, as always, when in doubt, consult with your veterinarian to ensure the best care for your beloved feline companion.
