Who Is Skye Blake?
Skye Blake, Cat Info Detective, is a curious cat researcher (not a veterinarian) who sniffs out expert, reliable sources about cats, studies their information, then passes it on to you!
Sometimes there’s not enough evidence for easy answers, so Skye gives you all sides, explains the situation as thoroughly and clearly as possible, and links you to experts on each page.
All sources are given at the bottom of each page so you can do more snooping…
First, Vet Visit
First things first. Get your buddy to the vet for a complete checkup.
Find out what’s wrong before deciding how best to treat his problem… CBD isn’t for casual use.
If you’re already working with a vet and have a good diagnosis but are frustrated with treatments that aren’t helping, ask about using CBD.
Some vets aren’t legally allowed to discuss it (see below), but others can.
What is CBD (Cannabidiol) Oil?
CBD oil has become popular for people, dogs and cats who have inflammation, pain, anxiety, and chronic conditions.
So, what is CBD oil?
Cannabidiol (CBD) is a compound extracted from the Cannabis sativa L. plant.
CBD oil is cannabidiol with carrier oils and sometimes other ingredient like flavorings.
Cannabis, Hemp, CBD & Marijuana
People use the terms “cannabis”, “hemp”, “CBD”, and “marijuana” interchangeably, which gets confusing.
Hopefully, this info will provide some clarity.
“Cannabis”, also called “hemp”, is a genus of flowering plants with a disputed number of species.
The main three are…
Cannabis species come in many different varieties, with over 100 active compounds, some having opposite effects from others.
The word “hemp” describes varieties of cannabis grown for industrial, non-drug use. Examples of these uses are rope and cat litter.
Cannabidiol (CBD) is a compound extracted from the Cannabis sativa L. plant that contains less than 0.3% THC.
Manufacturers use it in products like lotion, oils, treats/chews, and capsules.
Anecdotal and scientific evidence shows there are beneficial effects from CBD that lessen symptoms of various chronic conditions in people.
This makes CBD desirable, since it has benefits without the mind-altering chemical (THC) of marijuana.
So now pet owners are trying it for their dogs and cats with chronic and/or painful conditions.
The Legalization of Hemp
As part of the Agriculture Improvement Act of 2018 (2018 Farm Bill-Trump) the Hemp Farming Act of 2018 reclassified hemp (with less than 0.3% THC) from “Schedule I controlled substance” to “agricultural commodity”.
“Under the Hemp Farming Act, hemp cultivation is no longer limited to state departments and universities.
In addition, the act allows farmers rights to water, crop insurance, and federal agricultural grants, as well as legal access to national banking.
Hemp may also be transported across state lines.”1“Is Hemp Cultivation Legal in the U.S.?”, Weedmaps
Discover more about the history of hemp in the U.S. at “Hemp Cat Litter“.
Marijuana is the type of cannabis most people are familiar with that’s smoked as “joints”.
It contains the compound Delta-9 Tetrahydrocannabinol (THC) that creates a mind-altering “high” or euphoria in humans.
Marijuana typically contains from 2.5% to 25% THC. The more potent it is, the more dangerous it is.
THC is what makes marijuana an illegal controlled substance in some states and at the federal level in the U.S.
Marijuana & Cats Don’t Mix
If you think it’d be fun to watch your cat get “high”, think again! Humpf… what an offense to our feline dignity!
Ok, catnip makes us crazy… but not marijuana!
Catnip makes us kitties mellow and happy.
Marijuana makes us very sick…
THC can cause neurological problems that create fear and erratic, aggressive behavior.
Don’t feed it to cats in any form (including brownies).
Don’t smoke it around them, and don’t blow the smoke in any cat’s face!
There’s a documented case of a cat being made sick by marijuana smoke.
Find out more at “Marijuana intoxication in a cat“.
The Endocannabinoid System in Animals
All mammals, reptiles, fish, and birds have a system known as the “endocannabinoid system” (ECS). That includes us fabulous felines!
In this system is a chain of receptors (CB1 and CB2) in the brain, organs, glands, and nervous system that helps keep the body chemically balanced.
CBD interacts with these receptors in the bodies of humans and dogs, so it’s likely the same in us cats.
There is still much that’s not known about the endocannabinoid system.
Safety and effectiveness both for short and long-term use of CBD in humans or animals is currently being studied.
Many studies have been done over the last few decades about non-psychoactive cannabinoids, but were conducted with laboratory animals such as rats, not cats.
Theories abound that CBD oil will work well for cats with various conditions because they have the same ECS that humans, dogs, rats, and other mammals do.
Scientists are currently conducting studies specifically with cats about the effects of CBD on pain.
More studies are planned to determine if relieving anxiety helps deal with urinary tract infections (sure hope so).
Logically, the studies that are emerging about humans, dogs and CBD, lead people to think cats can respond in the same way to medical use of the oil.
Assuming that’s correct, it makes sense that we cats could get the same benefits from CBD oil as people and dogs do.
Veterinarians & CBD
Talking to your veterinarian about CBD is just as important as talking to your doctor.
But this may be difficult or even impossible. Here’s why…
Scientific Evidence (or Lack Thereof)
Many vets may not yet be up-to-date about the legal changes and use of CBD products.
Even if their knowledge is current, they’re justifiably reluctant to recommend using products that don’t have controlled, independent scientific studies to back those recommendations.
Vets are more comfortable using medications that have a good track record of success instead of something yet unproven (works for me, too).
Anecdotal stories of what people experience with their pets are helpful but not the same as clinical data.
In the case of CBD, there are other medications that have the backing of scientific studies already in use for the same conditions.
In some cases, though, these traditional treatments don’t work or have side effects that aren’t good for long-term treatment.
If that’s the case in your state or area and regular treatments aren’t helping relieve your cat’s pain and other symptoms, a holistic vet may be able to help.
Veterinary Legal Restraints
Another restraint on veterinarians is that some vet licensing boards forbid discussion of any cannibas treatments with clients.
Those who can discuss it, can’t prescribe or recommend any products. It’s illegal for vets to prescribe cannabis, since it’s a Schedule I drug, illegal by U.S. federal law.
Laws dealing with prescriptions have not yet (to my knowledge) been revised to make an exception for CBD products.
The changes in laws involved with cannabis have made the issue confusing, since some states have now made its use legal, even though it’s still illegal nationally.
If you live in a country other than the United States, check the laws in your area.
CBD – A Current Hot Topic
The veterinary community is currently discussing the CBD issue and will continue to review new information as it becomes available.
Legislatures, vet boards and vets themselves will have more ability to properly judge the use of CBD for all animals as more studies are completed and data becomes available.
Observations From Vets About CBD
While many vets are more conservative in their approach to new products like CBD and prefer to wait for the clinical data, some believe there’s enough anecdotal evidence to justify using CBD in some cases.
There are currently some vets who are experts in understanding and using CBD for animals.
Find out more from them…

CBD & Chronic Conditions in Cats
Below is a list of diseases and chronic conditions in cats that seem to be responsive to CBD in its various forms (oil/tincture, capsules, topical cream, treats).
Take your cat to a vet for a proper diagnosis before using CBD in any form.
Carefully consider purity, dosage amount, and the potency that’s appropriate for your cat’s condition before using any CBD product.
If your cat is on other medications, it’s important to talk to your vet and pharmacist before giving CBD to avoid harmful drug interactions.
There’s no oversight or uniform measurement of dosages, so you may be giving a more or less concentrated dose to your cat than you think you are.
Be sure the oil you buy has been lab-tested for quality of cannabis, levels of CBD vs. THC, and any contaminants like metals, bacteria, and fungus.
CBD oil has a reputation for helping cats who are anxious and stressed. (We have such demanding lives, you see!)
This can occur in specific situations (e.g., thunderstorms or vet visits, ahhh!) or as a chronic problem (e.g., feels like my world is out to get me!).
It’s best to first try alleviating stress, anxiety, and behavioral problems by giving your buddy a cat-friendly living environment.
Cat trees, scratching posts, window seats, and other environmental enrichment relieve territorial anxiety… always great to be able to sit up high and survey our world!
You can work on training, too, and even talk to a behaviorist, if necessary.
There are two types of arthritis… rheumatoid and osteoarthritis.
Osteo is more prevalent in cats, especially older ones.
Both cause pain and stiffness in joints.
Studies have been done showing CBD has properties that help prevent the spread of cancer and might be able to reverse a cancer’s growth in dogs.
This is promising for us cats but more research needs to be done.
Currently, CBD is useful for relieving side effects of chemotherapy and pain from the cancer itself.
Some people are using CBD oil to treat diabetes in people and animals, but it’s not known how well this works to stabilize blood sugars.
Changes in diet and exercise (with insulin injections, when needed) are still the most effective way to deal with diabetes.
Tissue inflammation is involved with a number of illnesses both in people and animals.
It’s often painful and difficult to eliminate.
Rheumatoid arthritis, asthma, and irritable bowel syndrome are a few such illnesses.
There are indications that CBD has powerful anti-inflammatory properties that might be helpful in many inflammatory conditions.
Being of the feline purr-suasion, I can tell you that we cats are masters at instinctively hiding pain and sickness.
So, if your cat isn’t wanting to walk much, walks with difficulty, has behavior changes, or hides an abnormal amount of time, get her to a vet… immediately.
IBS & Other Gastrointestinal Problems
The gastrointestinal system is susceptible to inflammatory problems.
Research done on humans using CBD oil for gastrointestinal problems indicates it should work well for dogs and cats.
But, again, there are no studies done yet confirming or refuting this.
Nausea/Vomiting/Loss of Appetite
When your cat isn’t eating, get him to the vet right away. Don’t assume he’s just being finicky.
He can go downhill quickly from organ problems after a few days of not eating.
CBD is known to help relieve nausea and vomiting for people, as well as stimulate the appetite.
This is assumed to be true with cats, as well, and is used in chronic conditions that cause these symptoms.
There’s some indication that CBD can treat symptoms of chronic kidney disease.
It’s not curable, but CBD oil is useful to help balance body chemicals that get out of balance when the kidneys aren’t able to work properly.
Pain is a symptom of many different physical conditions. Most pain can be eliminated by correcting the underlying cause.
Most people are familiar with taking aspirin, NSAID’s and other over-the-counter drugs to alleviate pain.
Generally, these are used as short-term remedies because of potential liver-damaging side effects. This is true for animals and people.
Chronic (recurring, long-term) pain is another story.
People and animals that have conditions that cause frequent or constant pain need remedies that have few or no side effects.
People use CBD oil/tinctures internally for both themselves and their pets for chronic pain.
Milder surface pain is handled with topical CBD cream.
Pancreatitis is a very painful inflammation of the pancreas that can kill your cat.
It makes it hard to digest food and requires veterinary help immediately.
To control pancreatitis, some vets use a combination of diet, enzymes, herbals remedies and CBD oil.
If your regular vet can’t or won’t consider CBD, a holistic vet may be able to help.
Seizures & Epilepsy
Seizures are scary and can be caused by various conditions, including epilepsy.
CBD is very effective in reducing seizures in people.
Scientists have done a study with dogs that shows it can be effective in cats as well.
Anti-seizure medications used for cats can stop seizures but are difficult for some cats to tolerate when used long term.
They can cause kidney and liver damage.
Find out more about seizures and CBD at “CBD Oil for Cats With Seizures and Epilepsy“.
As with people, my wise and wizened senior friends slow down and can get painful conditions like arthritis.
There’s anecdotal evidence from vets and cat owners that CBD oil has helped senior cats get relief from arthritis, asthma, urinary tract infection symptoms, as well as pain relief.
Upper Respiratory Infections
Some cats get upper respiratory infections (URI), often referred to as “colds”, frequently during the course of their lives (ah-choo!).
No studies have yet proven it but some veterinarians and cat owners have found CBD helps alleviate the symptoms of URI’s.
Urinary Tract Infections/FLUTD
Urinary system problems are often recurring, painful, and can lead to more serious problems.
It’s a major cause of kitties going in places other than the litter box.
Again, there are no direct scientific studies showing effectiveness.
Those who promote CBD believe it has anti-inflammatory, anti-bacterial properties.
Using CBD for Your Cat
Now that you have a better understanding of CBD and it’s uses, discover more about CBD products at ” Using CBD For Cats“.
As always, talk to your vet about your cat’s specific medical needs, especially if there are symptoms of any problem.

Sources used on this website are either primary or secondary.
Primary sources are always preferable and have the most reliable information because they’re original and directly referenced.
Scientific abstracts and data are good examples of primary sources.
Secondary sources are weaker because they usually consist of opinions or articles that give no sources of their own.
However, sometimes they refer to primary sources.
When I use secondary sources most are those with some authority, such as veterinarian or cat behaviorist books and articles.
