F:1 | Feline Elixir Plus
A full-spectrum blend of CBD, CBG, and THC, with natural catnip for palatability - created by an integrative veterinarian to help support your cat's comfort, calm, and everyday resilience.
Why F:1 is different
Unlike scaled-down canine products, F:1 recognizes that cats have unique physiological responses to cannabinoids and require feline-specific formulation - it isn't a smaller dose of a dog formula, it's built from the ground up around feline physiology and preferences.
F:1 is designed to help support your cat's comfort and mobility, encourage a healthy inflammatory response, promote calm behavior, and aid neurological and digestive function - gentle, whole-body support for cats facing everyday physical, emotional, or environmental stressors.
Because cats aren't small dogs, F:1 leaves out added terpenes and other canine-formulated ingredients that cats don't uniformly respond to - and includes a small amount of catnip, purely to help make the tincture more palatable.
Right:Ratio family
What's actually in F:1
F:1's cannabinoid profile is based on clinical response patterns observed in feline patients specifically - not adapted from a canine formula.
Cannabinoids
Why catnip?
100% natural, and deliberately included: cats aren't small dogs, so F:1 adds catnip to help make the tincture easier to give, rather than borrowing terpenes or other canine-formulated ingredients cats don't uniformly respond to. It's not a therapeutic ingredient in its own right - it's part of why this formula is built for cats from the ground up.
Ingredients: CBD, CBG, THC (<0.3%), and 100% natural Catnip.
Inactive Ingredients: 100% High Oleic Organic Safflower Oil.
What to consider when selecting F:1 for your cat
A good fit if your cat:
- Seems anxious, easily startled, or overwhelmed in a multi-cat household
- Is slowing down or seems less comfortable with everyday movement
- Has skin or coat changes, or seems itchy, that your vet is monitoring
- Your vet has flagged a digestive or urinary concern worth watching
Talk to your vet first if your cat:
- Has known or suspected heart disease - a cardiologist screening is recommended before starting F:1
- Is on other medications
- Has a new or worsening symptom that hasn't been evaluated
- Is under 1 year old

Find the Right FitEvery pet, individually.
Did your vet refer you? Does your cat have a complex medical history or unique needs? Our Custom program builds a formula specific to your cat - start with the intake form (first-time customers) or the Custom Reorder form.
1. Complete the intake form
Name, weight, breed, age, and other information related to your situation, including any referring vet comments.
2. We design the formula
Your cat's specific circumstance, along with vet input, if available, enable us to create a bespoke formula, grounded in the same rigorous science behind every Right:Ratio product.
3. We stay with you
Right:Ratio becomes a partner in care, providing dosing guidance, adjustments, and check-ins on your cat's progress.
Dosing & how to use
Start with the cat starting dose on the dosing guide, given twice daily with food. Geriatric and sensitive cats start lower.
Titrate at the interval set out in the dosing guide, watching for: steadier appetite, calmer behavior, more comfortable movement.
Once you see that improvement, hold at that dose - reach out anytime with questions, real support, not AI.
Give consistently once or twice daily - don't stop abruptly.
Shake well
Shake for 30 seconds before each use.
Give directly, or with a treat
Directly into the cheek pouch or rubbed on the gums works best; mixing into a high-value treat is fine too, though a higher dose may be needed.
Store properly
Store at room temperature, away from direct light.
Subscription frequency guidance
Not sure how often to reorder? Most cat parents start with a 6-week delivery. It's easy to change your frequency anytime.
Want more personalized guidance? See the dosing guide for feline-specific titration guidance, with a plan built around your cat's exact weight, age, and current dose. Keep your cat's profile up to date so we always have this on file, or email us directly with your cat's age, weight, and condition(s).
10 years optimizing our Custom support formulas.
Every Right:Ratio formula undergoes dynamic, rigorous development and third-party laboratory testing - grounded in natural, integrative care and evidence-based science.

Backed by research
A sample of the researchF:1's formula is grounded in the same clinical cannabinoid science behind every Right:Ratio product. The studies below are a representative sample, curated and maintained by the Veterinary Cannabis Society, an independent nonprofit - not written or funded by Right:Ratio.
Research tells the stories
At R:R, our approach isn't static - it's informed by the latest clinical research in veterinary medicine on the use and safety of medical cannabinoids, and our own +8,000 documented CROMs (Client-Reported Outcome Measures). These are not reviews - they're clinical touchpoints we conduct with every serious medical case we've handled in the last 10 years.

Calibrated, not counted.
Most other pet supplement brands compete on milligram count alone. F:1 is calibrated with the right combination of molecules, in exactly the right amounts, and in the right ratios - for the exact feline support your cat needs, alongside specific dosing and titration guidance.
Not a supplement guess. A clinical protocol.

Every Formulary batch is verified by an independent, state certified laboratory - and every batch's full lab report is published right here on this page.
F:1 independent lab certificate of analysis
A certificate of analysis (COA) is the independent lab's full report on one specific batch - which cannabinoids it contains and at exactly what levels, plus confirmation it's clear of pesticides, heavy metals, and residual solvents. It's how you see what the third-party lab actually found, not just what the label claims.

Right:Ratio F:1
"Our trusted and wonderful integrative vet recommended F1 for us, and so far it's been working wonderfully! She is responding really well to it, and it has even provided behavioral support - she gets less agitated when she sees outdoor cats near our home, which used to set her off."
Right:Ratio F:1
"After about a week he seemed to be eating more, and has become more cuddly and affectionate again - he now curls up next to me every morning, just as he did when he was a kitten. Last week he even played with some toys, which I haven't seen him do in years."
Right:Ratio Custom
"She has good sleep, eats well, her symptoms seem to have diminished."
FAQ
Will my cat feel "high"?
No - F:1's ratio is calibrated for feline physiology, not a psychoactive effect.
How long until I see a difference?
Give it a minimum trial of 3-4 weeks at an adequate dose before deciding whether F:1 is a good fit for your cat.
Is F:1 safe if my cat has heart disease?
Talk to your vet first - cats with known or suspected heart disease should be screened by a cardiologist before starting F:1.
Can I combine this with a vet-prescribed medication?
Talk to your vet first - see "Is This Right for Your Cat?" above.
