How Much CBD is Safe for Cats? 

CBD Oil Dosage for Cats

The basic CBD oil dosing rule for cats is 1-5 mg CBD for Every 10 Pounds of Body Weight. Most experts agree that CBD is safe for cats as long as you use the correct dosage. In fact, many CBD manufacturers recommend using twice the amount of CBD in cats than in dogs. This may seem scary at first, but there is a completely logical explanation. 

Namely, cats have fewer cannabinoid receptors, meaning they need more cannabinoids to experience the same potential benefits and effects.  

However, before introducing CBD products on your cat's menu, it is imperative you talk with your trusted veterinarian. Consulting with your vet is critical because CBD can interact with certain over-the-counter and prescription medications in terms of either boosting or inhibiting their effects. 

What is CBD Oil for Cats?

CBD is short for cannabidiol – a cannabinoid found in the Cannabis sativa plant. Manufacturers extract this compound and mix it with a carrier like a coconut oil

CBD oil for pets must be extracted from hemp plants and not from marijuana plants. The marijuana version of the cannabis plants contains high levels of tetrahydrocannabinol (THC) – a toxic and psychoactive compound. 

CBD works by mimicking the body's endocannabinoids, attaching with the cannabinoid receptors, and interacting with the endocannabinoid system (ECS) – a regulatory system present in all mammals. 

The ECS ensures homeostasis (a state of health and balance) by managing various body functions and processes, including appetite, sleep, metabolism, mood, inflammation, pain, etc. 

CBD oil Side Effects in Cats

Can I Give My Cat CBD Oil

If you accidentally give your cat a few extra CBD drops, your pet will probably experience some of these mild and short-lasting side effects. 

Dry Mouth: Even small amounts of CBD can decrease normal saliva production. As a result, you might notice that your cat seems thirstier than normal. Make sure to keep their water bowl full and within easy reach. 

Just do not forget – if your cat drinks more water than usual, it will also make more frequent trips to the litter box. 

Diarrhea: The CBD itself does not cause diarrhea, but the carrier oil might. Diarrhea is a widespread side effect when starting your pet on CBD oil or any other new supplement. The body needs time to adjust to new substances.  

You can minimize the risk of diarrhea by administering the CBD dose at mealtime. The carrier oil is more likely to cause diarrhea on an empty stomach.  

Lowered Blood Pressure: If you give your cat too much pet CBD oil, it may lead to a temporary drop in blood pressure. This drop can result in your cat feeling dizzy and lightheaded. 

To avoid these uncomfortable side effects, keep your dose within the recommended range and always practice gradual CBD introductions. 

Excessive Sedation: Many owners use CBD oil to help their pets relax or even get better sleep. But, if you administer too much, they may end up experiencing excessive sedation. 

The fatigue can be uncomfortable and make it hard for them to function as they normally would (especially in a busy environment). 

Basic Dosing Rule for Cats: 1-5 mg CBD for Every 10 Pounds of Body Weight

We recommend giving your cat between 1 and 5mg of CBD oil per 10 lbs of body weight. Of course, feel free to adjust this amount as necessary. 

For instance, if your cat is overweight or has a high tolerance to CBD, you may need a strong dose. On the other hand, it may require less than the recommended dosage if it is young or underweight. 

How much CBD oil you should give your cat ultimately depends on its body weight, overall health, and underlying health issues. 

Obviously, the lower ends of the 1 to 5 dosing specter are suitable for promoting overall wellness, immune system boosts and managing occasional pain and mild stress. The higher end is recommended for cats with more severe health issues by supporting the body's immune response.

CBD Dosage for Cats


When using cat CBD products, always start with a small dose and observe your cat's response. Over time, you can gradually increase the CBD amount as your cat gets used to the new supplement on its menu. 

Keep in mind that the effects of CBD in cats are often subtle. Therefore, if you do not notice a drastic change in your pet, refrain from increasing the regular dose. Sometimes, the effects can take around 30 minutes to kick in and usually last for around 4-6 hours.

Considering how long it takes the CBD to kick in and its effects last, it is normal to wonder when the best time to administer a CBD dose is? The answer depends on the situation and personal convenience. 

Some pet owners choose to administer CBD oil to their cats in the morning as this allows their cats to manage occasional stiffness once they wake up. Other cat owners prefer CBD administration at night since the relaxing properties can help cats unwind and settle in for a restful sleep.  

Finally, some owners use CBD oil for their cats on an as-needed basis. For example, if your cat has separation anxiety, the ideal CBD dosing time would be half an hour before you leave your pet alone. 

To ensure more robust CBD health benefits and effects, we recommend consistent CBD use. In these terms, you can give your cat a lower regular CBD dose for general wellness and use an extra CBD treat before potentially stressful situations (staying alone, car rides, thunderstorms, fireworks). 

Dosage Based on CBD Potency

CBD products for cats come in different forms and at different strengths. Basically, you should choose the combination that works best for your cat's needs. 

Oils and Tinctures: If you get a CBD oil or tincture, you may administer it orally. Some owners use the dropper to place the oil under their cat's tongue. This method can be effective and will speed up the absorption rate. However, not all cats are cooperative. 

To make things easier, consider administering the CBD doses at mealtime. Just ensure using tasty and deliciously smelling cat food to cover the CBD presence in the food bowl efficiently. 

Bites and Chews: Bites and chews are perhaps the easiest way to administer CBD to your cat, especially if notorious for her finicky eater habits. 

Our cat CBD treats are super tasty and contain a premeasured amount of 4 mg of CBD per treat. Available in cat-friendly flavors, they are easy to administer and can be used on the go. 

CBD Dosage Frequency for Cats

So, how often should you give your cats CBD oil? The answer depends on why you are using the CBD product in the first place. 

For example, if your cat suffers from inflammation, mild arthritis, or other types of pain, consider giving CBD once every eight hours. This CBD dosing frequency can help your cat maintain a normal inflammatory response and manage occasional discomfort. 

If the CBD use is to manage stress or offer immune system support, once or two doses per day will be enough to achieve results. At this frequency, your pet should be able to experience the full range of benefits while avoiding the potential side effects. 

How to Calculate a CBD Dose for Cats

When it comes to calculating the right amount of CBD, cats are much simpler than dogs. Namely, since cats are all the same weight, it is always the same dosage recommendation – 1 full dropper a day, from a 125mg potency, which translates to 4mg of CBD per day.

But what happens if your cat is not averagely sized? Well, the math is simple – if your cat is 20 lbs, it can receive anywhere between 2 and 10 mg of CBD oil per day. In more practical terms, that is half a dropper or two full droppers based on why you are using CBD oil. 

Finding a High-Quality CBD Oil for Cats

How do I Give CBD Oil to My Cat

Now that you know how to calculate the right CBD amount for your cat's individual needs it is time we help you choose the best pet CBD oil. 

With so many CBD manufacturers finding a reputable brand with high standards and premium quality CBD products can be challenging. To make the search simpler, here are the things you need to consider. 

Full Spectrum CBD Oil: Generally speaking, there are three main CBD oil options – full-spectrum oil, broad-spectrum, and CBD isolates. 

Always opt for the full spectrum variety as this CBD oil contains different cannabinoids and additional compounds (terpenes, flavonoids, essential fatty acids) which boost each other effects. 

CBD Hemp Oil: Pet CBD products must be extracted from the hemp plant and contain less than 0.3% THC. However, there is one more trick: hemp CBD oil and hemp seed oil should not be confused. 

Hemp CBD oil is made of different hemp plant parts, while hemp seed oil is made solely from hemp seeds. The seeds do not contain cannabinoids and consequently, their oil is not as beneficial as hemp CBD oil. 

Organic and Made in the USA: The best CBD oil is made in the United States, not just manufactured but also sourced. Ideally, the CBD oil should be made from organically grown hemp using CO2 extraction methods. 

All ingredients in the CBD product must be healthy, human-grade, and premium-quality. Keep in mind that GMO plants, soy, dairy, and corn are associated with health issues and are of questionable quality.   

Certificate of Analysis (COA): The CBD oil manufacturer should provide a Certificate of Analysis – an official document confirming the product has been third-party lab tested for contaminants such as heavy metals and microbes.  

The lab results will also provide a full breakdown of just how many cannabinoids are in your product, as well as the richness of their concentration. 

Reputable CBD brand: The brand's transparency is a good indicator of the quality of its products. A high number of good reviews and a good standing with the Better Business Bureau are preferred.  

Plus, a brand confident in the quality of its products will have a money-back guarantee policy. 

Honest Paws Suggested CBD Oil Dosage for Cats

If you look up CBD dosage for cats, each brand will have its own CBD dosage guidelines. When starting a cat on CBD oil, start with a small amount to see how they react and slowly work your way up to the recommended CBD dosage. 

At Honest Paws, all of our cat CBD oil products use the same bottle size. Each contains 125 mg of CBD per bottle.

The recommended dosage is one full dropper (which translates to 4 mg CBD). Seeing as all cats weigh about the same (around 10 lbs), this amount is perfect for any cat you have.
