Chronic kidney disease, or CKD in cats, is a progressive and painful metabolic condition marked by loss of renal function. The main symptoms of CKD in cats are lethargy, swelling, and changes in urination habits.

Cats with kidney disease are treated with a CBD oil dose between 2 and 4 mg per 10 pounds of body weight. Start with a lower dose and increase gradually until the cat is comfortable.

How Can CBD Oil Help Cats with Kidney Disease?

CBD oil helps cats with kidney disease by interacting with the endocannabinoid system (ECS) to ease the symptoms of the condition, which include lack of appetite, inflammation, back pain, lethargy, and swelling. 

The ECS is a regulatory system present in all mammals and is composed of endocannabinoids (neurotransmitters that affect body functions, like mood, pain, anxiety, appetite, inflammation, metabolism, memory, etc.). 

Understanding how CBD oil helps cats with kidney disease starts by answering “What is CBD?” for pets. 

CBD, or cannabidiol, is a compound extracted from the hemp variant of the Cannabis sativa plant. CBD oil for cats with kidney disease binds to and replaces the cat’s endocannabinoids and, by acting on the endocannabinoid receptors, helps relieve the symptoms of kidney disease in cats. 

What is Kidney Disease for Cats?

Kidney disease or Chronic Kidney Disease (CKD) in cats is a “persistent loss of kidney function over time, ” defined by Cornell University. Kidney disease is a chronic disease because the kidneys stop functioning over time.

Healthy kidneys perform vital roles, like filtrating the blood, balancing electrolytes, regulating hydration, and producing urine. Cats with kidney disease are unable to remove waste products. The buildup of waste products in the cat’s system results in sickness and high levels of toxicity in the blood. 

Chronic disease in cats is a progressive condition and eventually leads to kidney failure or complete loss of kidney function. 

What are the Causes of Cats’ Kidney Disease?

The causes of cats’ kidney disease are listed below.

  • Genetics: Polycystic kidney disease (PKD) and amyloidosis are hereditary conditions that result in kidney disease. PKD is widespread in Persian cats, and amyloidosis is common in Persian and Abyssinian cats. 
  • Severe Kidney Injury: Kidney disease develops in some cats after kidney injury caused by infections (feline immunodeficiency virus, feline infectious peritonitis) and toxin ingestion, such as antifreeze, pesticides, toxic plants like lilies or cleaning products. 
  • Underlying Conditions: Clotting disorders, strokes, some cancer types (lymphoma), and immune-mediated diseases culminate in kidney disease in some cats. 

What are the Symptoms of Cats’ Kidney Disease?

The symptoms of cats’ kidney disease are listed below. 

  • Lethargy: Weakness is a common sign of kidney disease. Lethargic cats sleep more and are disinterested in everyday activities. 
  • Swelling (Edema): Improper blood filtration and waste product retention lead to swelling or edema. 
  • Changes in Urination: Cats with kidney disease pass water more often in the early stages and less frequently as the condition progresses.
  • Increased Water Intake: Increased fluid loss in the early stages of kidney disease results in increased thirst and water intake. 
  • Vomiting & Nausea: Kidney disease nauseates cats and is a strong vomiting trigger.  
  • Painful Abdomen: Kidney disease is painful. The abdomen of cats with CKD is often swollen and painful. 
  • Weight Loss: The pain and vomiting associated with kidney disease reduce the cat’s appetite, which results in weight loss. 

How Does Kidney Disease Affect Cats Behavior?

Kidney disease affects cats’ behavior by increasing lethargy and fatigue because the buildup of toxins in the bloodstream triggers nausea and pain, which results in a lack of interest in everyday activities. 

Changes in the cat’s usual behavior, such as dizziness, changes in urination, or swelling, warrant veterinary attention for early diagnosis of kidney disease and prompt treatment. 

What is the Normal Treatment for Cats with Kidney Disease?

The normal treatment for cats with kidney disease includes intravenous fluid therapy, symptomatic support, and dietary supplements. 

Intravenous fluids are used to correct electrolyte imbalances, help the body flush, eliminate toxins, and promote faster distribution of medications. 

The symptomatic therapy depends on the symptoms and involves anti-nausea medication, appetite stimulants, pain medications, and anti-inflammatories. 

Cats with kidney disease benefit from specific dietary changes to food with low sodium and moderate. Diets designed to relieve pressure on the kidneys help reduce symptoms of kidney disease.  

Veterinarians prescribe dietary supplements to support kidney and liver function, as the liver is overworked in cats with renal problems. 

How to Make a Cat with Kidney Failure Comfortable Using CBD Oil?

To make a cat with kidney failure comfortable using CBD oil, follow the steps below.

  1. Find The Right CBD Oil. Many brands are offering CBD oils for cats. Choose brands that source full-spectrum CBD, supply a Certificate of Analysis from a third-party laboratory, and have positive customer reviews. Try several products to determine which one works best for the cat’s kidney disease symptoms. 
  2. Implement Different CBD Products. Try alternative CBD products if the cat rejects CBD oil. Cat CBD treats with flavors or mixing CBD powder with cat food makes dosing easier. 
  3. Modify the CBD Dose. Start with a lower CBD dose to give the cat time to adjust. Increase the CBD dose gradually. The goal is to find the dose that manages the cat’s symptoms without causing side effects. 
  4. Be Consistent with CBD Use. Cannabidiol needs time to take effect and works best when used uniformly. CBD for cats is safe to use on a daily basis. 

Stick to the veterinarian’s guidelines regarding mainstream kidney disease treatment. CBD for animals is natural and typically safe to combine with other medications. 

How Much CBD Oil Can a Cat Have for a Day?

The amount of CBD Oil a cat can have for a day is between 2 and 4 mg for every 10 pounds of body weight. Start with a lower dose and gradually increase the CBD amount if necessary. 

Each CBD product has specific dosage recommendations based on the CBD concentration in the oil, treat, powder, cream, or patch.

Do not worry in case of accidental use of high CBD doses, as hemp cannabis supplements do not cause overdoses in pets.

Consult a veterinarian before adding CBD to the kidney disease treatment plan. Use a CBD dosage calculator to find the best starting CBD dose for the cat’s age, weight, and overall condition. 

How to Choose the Right CBD Oil for Your Cats?

To choose the right CBD oil for your cats, follow the steps below.

  1. Choose an Extract Type. CBD for cats with kidney disease must be full-spectrum. Full-spectrum oils contain various cannabinoids alongside other entourage compounds, such as flavonoids, terpenes, and fatty acids. 
  2. Confirm the THC-Free Profile. CBD products for cats must be made from hemp and not marijuana. Hemp is low in THC (tetrahydrocannabinol), while marijuana contains high levels of THC. THC is toxic to pets. 
  3. Check the Certificate of Analysis (COA). The certificate of analysis is a third-party laboratory declaration confirming that the pet CBD product is effective, pure, and safe. The COA shows the amount of cannabinoids within the oil. 
  4. Pick a Pet-Specific Formulation. The CBD oil must be formulated exclusively for cats. Human cannabidiol supplements often contain potentially harmful ingredients such as xylitol or chocolate. 
  5. Research the Brand. Research the pet CBD brand. Reputable brands are transparent and display the COAs and reviews from other customers.  

Is CBD Oil Safe for Cats with Kidney Disease?

Yes, CBD oil is safe for cats with kidney disease. “CBD is a well-tolerated supplement,” according to Colorado State University.

The answer is yes for Pet owners who ask, “Is CBD safe for animals?” or “Is CBD oil safe for cats?” Pet CBD products are safe and health-boosting when used in accordance with the manufacturer’s recommendations.

Cat CBD oil and treats for cats with kidney disease are made from the hemp variant of the cannabis plant. Cat CBD does not contain THC as a psychoactive compound, meaning it does not make pets “high.”

Can CBD Oil Treat Kidney Disease?

No, CBD oil does not treat kidney disease, but it helps with the symptoms. 

Studies show CBD helps with several kidney disease issues, including nausea, pain, inflammation, and anxiety. Managing these symptoms improves the cat’s quality of life. 

CBD oil has anti-nausea and anti-vomiting effects that help improve appetite in cats with kidney disease. 

Cannabidiol has an anxiolytic effect and mimics the work of serotonin, thus relieving stress. 

CBD has strong anti-pain and anti-inflammatory features beneficial to cats suffering from kidney disease. 

Are there Any Other CBD Products aside from CBD Oil?

Yes, there are five other CBD products for cats, including cat CBD treats, cat CBD capsules, cat CBD powders, cat CBD creams, and cat CBD patches. 

CBD treats are formulated with CBD oil and cat-friendly ingredients. Treats for cats with kidney disease are convenient, feature flavors that appeal to cats, and come in premeasured doses. Here are the 7 best CBD cat treats.

CBD capsules are oral supplements but are not practical to administer to cats. Cats are notorious for being picky eaters and dislike swallowing pills, which makes the use of CBD capsules challenging. 

CBD powders are an alternative to CBD oils. Powders are mixed with cat food and are hard to notice, even by picky cats. CBD powders for cats feature flavors cats like and are very straightforward to use. 

CBD creams and balms are the most popular topical CBD products. Topical CBDs for cats are practical and easy to use. Apply the CBD topical and entertain the cat until the product is absorbed into the skin. Licking the cream is not toxic or dangerous but diminishes overall efficacy. 

CBD patches are applied to the naked skin and release cannabinoids when in contact with body heat. CBD patches are not suitable for very hairy cats and cats that are hyperactive.  

What are Other CBD Oil Treatments for Cats?

Other CBD oil treatments for cats are listed below. 

  • CBD Oil for Arthritic Cats: CBD has anti-pain and anti-inflammatory features that are helpful for cats with arthritis. Cats supplemented with cannabis are more active and comfortable. 
  • CBD Oil for Anxious Cats: CBD features anxiolytic properties and supports natural calmness and relaxation. Cannabis products for cats with anxiety are a natural alternative to anti-anxiety medications. 
  • CBD Oil for Seizure Prone Cats: CBD for cats has strong antiepileptic and anticonvulsant features, reduces neuroinflammation, helps normalize brain rhythm, and acts as a neuroprotectant.
  • CBD Oil for Cats with Cancer: Cat CBD is a promising anti-cancer drug. Cannabinoids help destroy cancerous cells, shrink tumors, promote cancer cell death (apoptosis), and prevent metastasis. 

The effects of CBD on cats with chronic kidney disease are similar to those on cats with cancer. CBD is not a miracle cure for CKD or cancer, but CBD supplementation helps relieve the symptoms, and in cancer cases, CBD supports traditional medication to battle the cancer. 

CBD helps shrink tumors in cats with cancer, accelerates cancer cell death, destroys cancerous cells, and prevents cancer from spreading. Traditional cancer treatment in cats is chemotherapy and radiation. CBD helps relieve nausea caused by chemotherapy and radiation and stimulates the appetite in cancerous cats. 

CBD helps manage the symptoms of kidney disease in cats. Like cancer, CBD promotes appetite, reduces nausea and inflammation, and overall pain relief.

CBD’s positive health effect against cancer is stronger than kidney disease because studies show CBD helps fight cancer in animals, whereas CBD in cats with kidney disease helps manage the symptoms.
