Can I give my cat the same CBD oil I use myself?

Choose a pet-formulated product instead. Pet CBD oils use carrier oils and strengths chosen for animals, while products made for people can include flavourings, sweeteners, or essential oils that were never evaluated for cats. If you are unsure whether a specific product is appropriate, bring the label to your veterinarian before giving any of it.

Is the starting dose the same as for a dog?

The commonly published starting tiers are expressed the same way — milligrams of CBD per pound of body weight per day — but cats are smaller than most dogs and process many compounds differently, so the same tier produces a much smaller absolute dose. Most owners begin at the low tier, hold it for a week, and only adjust after observing their cat. Your veterinarian is the right person to confirm a starting point.

How do I actually give CBD oil to a cat?

Most owners mix the measured dose into a small amount of wet food or a favourite treat, once daily to start. Giving it with food also makes the amount easier to keep consistent from day to day. Keep the routine boring: same time, same amount, for at least a week, and note what you observe.

What should I watch for after a dose?

The most commonly reported effects in pets are drowsiness and mild digestive changes. If you notice anything that concerns you — unusual lethargy, vomiting, or a change in appetite that persists — stop and contact your veterinarian.

Your cat's weight

Dosing tier

These tiers reflect commonly published weight-based starting ranges — they're guidance for a starting point, not prescriptions. Because cats are small and individual, most owners begin at the low tier and hold it for a week.

Product strength

A 30 ml bottle holds roughly 600 drops; a full 1 ml dropper is about 20 drops.

Suggested starting dose

0.5 mg/day

≈ 0.06 ml per day of your 250 mg / 30 ml oil — roughly 1 drop.

Start low, go slow

Mix the starting dose into a small amount of wet food or a favourite treat, once daily.
Observe your cat for a week: energy, appetite, digestion, behaviour, litter-box habits.
Then adjust gradually if needed, one small step at a time. If anything seems off, stop and speak to your veterinarian.

How weight-based dosing works

Published starting-point guidance for CBD and pets is almost always expressed per unit of body weight. This calculator uses the same commonly published weight-based tiers as our dog calculator — 0.05 mg per lb for the low tier, 0.125 mg per lb for medium, and 0.25 mg per lb for strong — multiplied by your cat's weight. Because cats are small, the absolute numbers come out genuinely tiny: for a typical 10 lb cat the low tier works out to about 0.5 mg per day. That is the point of starting low. These are starting-point ranges people commonly use, not prescriptions, and individual cats vary.

The second half of the tool is unit translation. Pet CBD oils are labelled by total milligrams per bottle, so a 250 mg / 30 ml oil works out to about 8.3 mg per ml. A standard dropper holds roughly 1 ml, which is about 20 drops — so the calculator converts the daily milligrams into an approximate ml and drop count for the strength you choose. The result is a starting point, not a prescription.

Cats are not small dogs

Cats process many compounds differently than dogs and people do, and less published research exists on CBD in cats than in dogs. That is a reason for more caution, not less: choose a pet-formulated product, avoid anything containing essential oils or flavourings that were not intended for cats, prefer products whose batch lab report verifies the THC content, and involve your veterinarian before you start. Our careful owner's guide to CBD for cats covers how cats differ and what to look for on a label.

Your veterinarian comes first

This tool provides general informational guidance only, not veterinary advice. Always consult your veterinarian before giving CBD to your pet, especially if your cat takes medication or has a health condition. Your vet knows your cat's history — medications, liver and kidney function, age, and breed considerations — that no web calculator can account for. Whatever you decide together, the universal advice holds: start low, go slow, give once daily for a week, observe, then adjust.
