We've worked with thousands of pet parents over the years, and one thing is clear: when CBD is safe, properly formulated, and given in the right amount, it can support calmer moods, ease everyday aches, and even improve skin and coat health.

What this article covers:

Is CBD Safe for Cats?

CBD can be a safe and effective option for cats when the right products are used. We've seen countless cats respond well, enjoying calmer moods, easier mobility, and better overall comfort. Side effects are uncommon, but things like mild digestive upset or a little extra drowsiness may happen in some cases.

It's always smart to check with your veterinarian first, especially if your cat takes other medications or has ongoing health concerns. From our experience, the most important factor is quality. A product that's pure, lab-tested, and clearly labeled gives you peace of mind and helps ensure the best results for your cat.

How Can CBD Help Cats?

CBD interacts with the endocannabinoid system, which in cats (as in other mammals) helps regulate a number of bodily functions: immune response, inflammation, mood, pain, etc. From what we've seen, CBD may help cats by:

  • Reducing anxiety (e.g. from storms, separation, travel)
  • Easing discomfort or pain (arthritis, inflammation)
  • Supporting skin health (itchiness, irritation)
  • Possibly aiding in calming for older cats who are stiffer or less mobile

These are among the most common areas where cat owners report improvements after consistent use.

Best CBD for Cats

Here are four King Kanine products that stand out. We picked them because of their formulation, lab testing, user feedback, and how they address different needs:

1. King Kalm CBD 75mg

Our King Kalm 75mg formula is designed for smaller cats or those just starting out with CBD. It delivers a gentle strength that makes dosing easier and safer when you're figuring out what works best for your pet.

We've tested it extensively and love the combination of broad-spectrum CBD with krill oil and hemp seed oil, which helps with absorption and adds extra nutritional value.

It comes with a dosing chart and oral syringe, so you can measure precisely. Most cats do well with this oil, especially when it's mixed into food or given directly to the mouth. The lower potency gives you more flexibility to adjust gradually and find your cat's sweet spot.

Our customers have used this formula for their cats, both young and old, to help them with their anxiety and skin issues.

2. King Kalm CBD 150mg

When a cat is larger or needs stronger support, our King Kalm 150mg formula can be the right fit. It packs more CBD into each milliliter, which can be especially helpful if you're looking for the best CBD for cats with anxiety or noticeable discomfort.

We've used this formula with cats that needed a bit more than the 75mg strength, and the improvement in their comfort and behavior was clear.

It has the same reliable features we insist on across our line, including krill oil for absorption and third-party lab testing for safety. Because it's more potent, careful dosing is essential, and we always suggest starting small and monitoring your cat's response during the first few days.

3. King Kalm CBD Mange & Mite Management Spray

Not all cat issues start inside the body, and that's why our King Kalm CBD Mange & Mite Management Spray exists. We created it to target mange, mites, and ringworm, all of which can leave a cat itchy, irritated, and uncomfortable.

In our testing, this topical reduced scratching, calmed irritation, and helped coats look healthier over time. It stands out because it blends broad-spectrum CBD with soothing ingredients like aloe vera, antibacterial agents, and a light lemongrass scent.

The formula is alcohol-free and designed to be gentle on sensitive skin. For cats that need external relief, this spray offers an easy way to help without oral dosing.

4. KING KALM 600mg CBD with Copaiba, Krill Oil and DHA for Dogs & Cats

This is our strongest formula in the King Kalm range, created for pets that need serious support with mobility, inflammation, or chronic discomfort. King Kalm 600mg CBD combines CBD with Copaiba essential oil, which enhances calming and anti-inflammatory effects, plus DHA from fish oil for skin, joint, and brain health. It's an excellent option for older cats that need a little extra help staying comfortable day to day.

Because it's so concentrated, dosing must be done carefully, and most cats will only need a very small amount. We always recommend starting with the lowest suggested dose and adjusting slowly while watching your cat's response.

How to Choose the Best CBD for Your Cat

Here's what to think about. We call these the “must-check factors” because from our years in the industry, getting these right makes the difference between a good outcome and disappointment or worse:

1. Purity & Lab Testing

Purity is everything when it comes to CBD for cats. Always look for products that are third-party tested, ideally with CO₂ extraction.

The reports should confirm the product is free from pesticides, heavy metals, and residual solvents. Brands that share batch-specific lab results show accountability and give you confidence that you're getting something safe.

2. Spectrum

The type of CBD spectrum matters. Broad-spectrum products, like the ones we offer, include a variety of beneficial compounds without unnecessary extras.

From our experience, broad-spectrum provides the best balance for cats, delivering consistent calming and comfort effects while staying gentle. Isolates can feel one-dimensional, and full-spectrum isn't always the most suitable choice for sensitive pets.

3. Strength/Potency

Strength directly affects how effective CBD will be for your cat. Smaller cats usually benefit from lower strengths, while larger or more symptomatic cats may need a higher concentration. The key is matching potency to your cat's needs and adjusting slowly. Reliable products include clear dosing charts so you can avoid guesswork and give your cat exactly what's appropriate.

4. Carrier Oils & Additional Ingredients

Carrier oils make a big difference in how well CBD is absorbed. Options like krill oil, hemp seed oil, or MCT oil help the body use CBD effectively and also provide added nutrition.

Extras such as Copaiba or omega fatty acids can support skin, joint, or immune health. Always check that ingredients are safe for cats and free from irritants.

5. Delivery Method & Ease of Dosing

How you give CBD is just as important as the product itself. Oils with syringes make it simple to measure accurately, while sprays and topicals are great for skin and coat issues.

Some cats accept oils in food, while others prefer a quick oral dose. Choosing the right delivery method ensures your cat actually gets the benefits without stress.

Benefits of CBD for Cats

Here are some of the key benefits we've observed (and that the pet-wellness community reports) when the best CBD for pets is used thoughtfully for cats:

  • Reduced anxiety and stress: CBD can help calm cats during scary events (thunderstorms, vet visits, travel) and moderate behavioral responses.
  • Pain relief and inflammation support: Especially in older cats or those with arthritis, joint stiffness, or general discomfort.
  • Improved skin health: It may soothe itchiness, reduce irritation, and improve coat condition. Topicals or sprays can help here.
  • Enhanced comfort in senior cats: Including better mobility, more relaxed rest periods, and possibly improved appetite or energy.
  • Support in everyday wellness: Some owners notice more regular behavior, improved mood, or fewer stress-related habits (overgrooming, nervous pacing).

These benefits aren't guaranteed, and the extent depends on the quality of the product, correct dosing, and consistency. But from our experience over many years, for many cats, these are the improvements we see first.
