Cannabis plants contain more than 100 active compounds, but the one most often used for medicinal purposes is cannabidiol, or CBD. CBD differs from cannabis’s major active compound, tetrahydrocannabinol (THC), in that it does not have a psychoactive affect, meaning it will not get users “high.” CBD oils contain a high concentration of CBD and can be used for therapeutic purposes.

“There are not many classical medical studies that explore the effects of CBD oil in cats,” says Dr. Daniel Inman, a veterinarian at Burlington Emergency Veterinary Specialists in Williston, Vermont. “While we don’t recommend CBD oil for our patients, holistic veterinarians are using it to treat a variety of ailments, including inflammation, anxiety and pain.”

Inman is careful to specify that CBD oil is often used to subjectively increase comfort and improve quality of life in pets, not necessarily cure ailments. This type of treatment should be advised by your veterinarian and not initiated without their consent.

Although there have been no scientific studies that specifically investigate the impact of cannabis on pets, Dr. Gary Richter, a holistic veterinarian and owner and medical director of Montclair Veterinary Hospital and Holistic Veterinary Care in Oakland, California, says that CBD oil is generally safe for cats. However, there can be some adverse effects to giving your cat CBD oil, including gastrointestinal upset and some sedation, both of which can be relieved by discontinuing the use of the oil.

Also, it’s worth nothing that while CBD oil is typically quite safe for cats and dogs, cannabis plants are not. “There is plenty of documentation of marijuana toxicity in cats, for those that nibble on the plants,” Guess says.
