Dosing a cat is all about restraint. Cats are small, sensitive, and particular, so the goal isn't a big dose — it's the smallest amount that helps, mixed into something they'll happily eat. At HempMy Pet we formulate a gentle, cat-appropriate hemp oil on our Colorado farm and coach owners to start low and go slow. Here's the whole picture: the formula, a weight chart, how to convert it to drops, and how to give it to a cat who has opinions about everything.
The CBD Dosing Formula for Cats
Cats aren't small dogs — they metabolize compounds differently and need much less. A widely used gentle starting point is roughly 0.1–0.25 mg of CBD per pound of body weight, given once or twice a day. Begin at the bottom of that range. Because a healthy cat is usually 8–12 lbs, most cats start somewhere around 1–3 mg of CBD total per day — a tiny amount.
The safety research in cats is reassuring here: a study of escalating cannabinoid doses in healthy cats found CBD generally well tolerated, and a separate long-term feeding study reported the same. That gives you room to start low without worry and adjust up only if your cat needs it.
CBD Dosage Chart for Cats by Weight
Start in the left column and only move up if needed. These are total CBD amounts, not drops.
| Cat's weight | Gentle start (~0.1 mg/lb) | Stronger support (~0.25 mg/lb) |
|---|---|---|
| 5 lbs | ~0.5 mg | ~1.25 mg |
| 8 lbs | ~0.8 mg | ~2 mg |
| 10 lbs | ~1 mg | ~2.5 mg |
| 12 lbs | ~1.2 mg | ~3 mg |
| 15 lbs | ~1.5 mg | ~3.75 mg |
These are total CBD, not drops. How many drops that is depends on the strength of your oil — that's the next step.
How Many Drops Is That?
Our 250 mg hemp oil comes in a 1 fl. oz. (30 ml) dropper bottle of roughly 600 drops, which works out to about 0.4 mg of CBD per drop. So a typical 10-lb cat starting at ~1 mg needs only about 2–3 drops — you can see why "start low" is so easy to overshoot with a cat. Our gentle 100 mg coconut oil comes as a jar you stir a small amount into food, which many cat owners find even easier than a dropper. Every product page lists its own serving guidance.
How to Give a Cat CBD Oil
The reliable way to dose a cat is in food:
- Mix it into wet food. A few drops of oil or a small dab of the coconut formula stirred into a favorite wet food is the easiest, least dramatic method.
- Start at the low end of the chart for your cat's weight and hold there for several days to a week.
- Give it daily and adjust in tiny steps — a single drop at a time — only if you feel your cat needs more.
- Don't force the dropper. A stressed cat isn't a calm cat; food-mixing keeps it positive.
Does the Amount Change by Reason?
The weight-based chart is your baseline for any goal. Where you land within the range depends on why you're giving it:
- Everyday wellness & calm: most cats do well at the gentle-start end. For a known stressor like a vet visit or car ride, some owners give a dose about 30–60 minutes ahead. See our calming support options.
- Ongoing support: give it daily and consistently — the fuller benefit builds over one to two weeks.
How Long Does It Take to Work?
When mixed into food, many owners notice a calmer cat within about 30 to 60 minutes. For ongoing support like everyday calm or senior comfort, the steadier benefit shows up with daily use over one to two weeks, as your cat's endocannabinoid system settles into a rhythm.
Can You Give a Cat Too Much CBD?
Full-spectrum hemp under 0.3% THC is non-intoxicating and has a wide safety margin — the cat dosing studies above tolerated escalating and long-term daily amounts. If you give more than your cat needs, the most common signs are simply mild drowsiness or a little GI upset, which pass on their own. Two real cautions: never give a cat a human CBD product (which may contain THC or unsafe additives), and if your cat is on medication, talk with your vet first, since CBD can affect how the liver processes some drugs.

How often per day — and can I give a higher amount?
Most cats do best when their daily amount is split into two servings, one in the morning and one in the evening. Splitting keeps support steadier through the day than a single serving. The starting range on the chart above (about 0.1–0.25 mg per pound, or roughly 0.2–0.5 mg per kilogram) is a gentle entry point for everyday wellness and calm support. Cats that are older, larger, or more active can gradually work up toward a higher maintenance level — up to about 0.5 mg per pound (roughly 1 mg per kilogram) per day — as long as you increase slowly and watch how your cat responds. Hold each amount for 3–5 days before adjusting, and only move up if your cat is tolerating it comfortably.
