CBD for cats: our university research and other published studies
Supporting university research into CBD and other cannabinoids in animals since 2019.
These selected publications cover feline receptor biology, CBD tolerability and clinical research. None tested Pet Routine for Cats or establishes that this oil treats disease. Research preparations and routes of administration differ from this product.
Formula Swiss-funded university research
Our research at the University of Bologna
From 2019 to 2021, Formula Swiss funded Professor Roberto Chiocchetti's research at the University of Bologna. His team mapped cannabinoid receptors in the mouth, stomach and intestines of cats. Both publications acknowledge Formula Swiss funding.
Receptor levels differed in healthy and inflamed mouth tissue.
What they did
Researchers compared mouth tissue from 16 healthy cats and cats with chronic gingivostomatitis.
What happened
Found cannabinoid and related receptors in the lining of the mouth, with markedly higher levels in cats with chronic gingivostomatitis, a painful inflammation of the mouth.
Good to know
Tissue samples from 16 cats; no CBD product treatment, effectiveness or dosage was tested.

What other CBD studies in cats found
Eleven selected publications, grouped by topic. Early findings are promising in some settings, but small studies and different preparations limit what we can conclude. A placebo is a dummy oil or paste without the active cannabinoids, used for comparison.
Twenty-two cats received CBD powder or placebo for 15 days around dental extraction, alongside standard pain treatment.
What happened
Cats given CBD for 15 days, starting just before tooth extraction, improved significantly more on a disease activity score than cats given placebo. Pain scores also fell further, but that difference was not statistically significant.
Good to know
Twenty-two cats; CBD was one part of a treatment that included tooth extraction and pain relief, and the results apply to the tested CBD powder.
Less rescue pain relief was needed during surgery.
What they did
Twenty-two cats received CBD or dummy oil before spaying, in addition to their usual anaesthesia and pain management.
What happened
None of the cats given CBD needed extra pain relief during the operation, compared with four of ten given placebo, and they were more sedated before surgery. Pain after surgery was largely similar.
Good to know
Twenty-two cats and one dose before surgery; all cats still needed morphine afterwards.
Anaesthetic requirements fell in this small study.
What they did
Researchers measured anaesthetic requirements in 16 healthy cats before and after a single CBD dose.
What happened
A single dose of CBD oil reduced the amount of inhaled anaesthetic cats needed by 11%. Heart and breathing rates were higher at the time of measurement.
Good to know
Sixteen healthy cats, one dose given by stomach tube and no placebo group.
Researchers measured absorption after a CBD-rich hemp oil and monitored eight healthy cats during 12 weeks of use.
What happened
CBD exposure was lower in cats than in dogs. Cats sometimes licked or shook their heads after dosing; one had a persistent elevation in a liver enzyme.
Good to know
Small healthy-animal study; not evidence of effectiveness for a disease. Do not assume equivalent responses across species.
Twenty healthy cats received escalating doses of CBD, THC, combined oils or a dummy oil under blinded monitoring.
What happened
No clinically significant blood-test changes were found. Mild temporary side effects occurred; neurological signs were more common with THC-containing oils.
Good to know
Twenty cats across five groups; mild adverse events occurred. Findings depend on the tested oils and do not establish routine doses.
Kulpa et al. · Journal of Feline Medicine and Surgery · 2021
The paste was absorbed and tolerated during a short trial.
What they did
Eight healthy cats received a CBD/CBDA-rich paste. Researchers measured blood concentrations and monitored one week of twice-daily use.
What happened
Cats absorbed the cannabinoids from the paste, and a week of twice-daily use caused no behavioural or neurological side effects or clinically relevant changes in blood tests.
Good to know
Eight healthy cats for one week, with no placebo group. The paste's manufacturer funded the study.
Wang et al. · Frontiers in Veterinary Science · 2022
Eight healthy cats received different single oral doses of purified CBD, separated by washout periods.
What happened
Single doses of up to 80 mg per kg of body weight were well tolerated; reactions were limited to head shaking, lip smacking and drooling just after dosing.
Good to know
Eight research cats and single doses only; this does not show that repeated use is safe or indicate a dose to give.
Rozental et al. · Journal of Veterinary Pharmacology and Therapeutics · 2023
Longer-term use was monitored, with important limits.
What they did
Randomised, blinded trials compared daily CBD with a dummy oil, including a 26-week study in healthy cats.
What happened
The tested CBD distillate was generally tolerated over 26 weeks among cats completing the trial. Blood-test results were broadly comparable with placebo.
Good to know
Healthy cats and one tested distillate only. Two CBD-treated cats had raised liver enzymes during the shorter study and did not enter the 26-week trial. Monitoring remains important; the results do not prove disease benefits.

Questions about our CBD oil for cats
What is in Pet Routine for Cats?
Each 30 ml bottle contains 900 mg CBD (3%) in MCT carrier oil, with a 0% THC specification. The ingredient list is Caprylic/Capric Triglyceride and Cannabis sativa L. extract. See the product laboratory report for the tested sample.
Is this the 2026 formula?
Yes. This is our 2026 Pet Routine for Cats formula. Formula Swiss has produced CBD products in Switzerland since 2013. Customer reviews may describe earlier oils, including different carrier oils or flavours.
How do I use Pet Routine for Cats?
Remove the protective film and shake well before use. Apply the drops directly to the cat’s skin, following the instructions supplied with the bottle. This product is for animal use only. Oral ingestion does not correspond to its intended use; do not add it to food or give it by mouth.
How many drops should I use for my cat?
Start with 1–2 drops, 1–2 times per day. Adjust gradually over time according to your cat’s response and your vet’s advice. Follow the directions supplied with the product.
Can I use it alongside my cat’s medicines?
Ask your vet before use, especially if your cat takes medicines or has a health condition. CBD can interact with medicines. Do not stop or change prescribed treatment. Do not use in pregnant or breeding animals, and stop use if an adverse reaction occurs.
Is Pet Routine for Cats a registered medicine?
No. Pet Routine for Cats is not a registered veterinary medicine and is not intended to diagnose, treat, cure or prevent disease. It is not a substitute for veterinary care or prescribed medication.
Did the university studies test this cat oil?
No. The two Formula Swiss-funded University of Bologna publications mapped cannabinoid receptors in feline tissues. Other teams investigated different CBD preparations. None of these publications tested Pet Routine for Cats or proves benefits for this 2026 formula.
Can I use the dog or horse oil for my cat?
Choose the formula labelled for your animal. Pet Routine for Cats contains 3% CBD, while the dog and horse formulas have different strengths and cannabinoid profiles. Do not transfer their directions or research doses to your cat.
