CBD for cats in South Africa — what’s different about cats

The single most important sentence in any cat-CBD article: cats are not small dogs. Their liver metabolism is materially different, their tolerance window is narrower, and products designed for dogs (or worse, humans) can be actively toxic to cats. This is the SA cat-owner’s starting guide.

Talk to your vet before starting CBD for your cat — especially if she is on any other medication, is elderly, or has known liver or kidney issues.

Why cats are different

Cats are obligate carnivores with a markedly reduced ability to conjugate compounds via glucuronidation — the liver pathway that handles most drugs. Combined with lower CYP enzyme capacity, this means:

• Cats metabolise CBD more slowly than dogs. Effects last longer; doses stack.
• The therapeutic window is narrower. A cat-safe dose is closer to the cat-toxic dose than in dogs.
• Common pet-CBD additives that are fine for dogs — certain essential oils, citrus flavourings — can be toxic for cats.

The Deabold et al. 2019 pharmacokinetic study showed cats need slightly higher mg/kg doses than dogs to reach the same blood levels — counter-intuitively — but the tolerance ceiling is lower. The practical translation: start very low, titrate slowly, watch closely.

Suggested dose ranges

Use the pet CBD dose calculator to work out drops by bottle strength. Per-kg starting ranges:

• Wellness baseline: 0.1–0.25 mg/kg twice daily.
• Joint comfort: 0.25–0.5 mg/kg twice daily.
• Chronic anxiety: 0.1–0.25 mg/kg twice daily.
• Situational anxiety: 0.25–0.5 mg/kg, 30–60 min pre-stressor.

Conservative daily ceiling for cats: 2 mg/kg/day. This is tighter than the dog ceiling because cat efficacy data is sparser and toxicity literature is more cautious.

Things to never put in a cat

• Xylitol — the artificial sweetener sometimes added to human CBD edibles and tinctures. Toxic to cats and dogs at low doses.
• Essential oils at non-trace concentrations — tea tree, peppermint, citrus, eucalyptus, cinnamon. Cats lack the enzymes to clear these and accumulate them.
• Citrus or chocolate flavourings. Citrus oils are hepatotoxic to cats; chocolate (theobromine) is toxic at lower thresholds than in dogs.
• Human CBD oil with food flavours. Even if the CBD itself is fine, the carrier and flavour may not be.
• Full-spectrum CBD with measurable THC. Cats are far more sensitive to THC than dogs — isolate or broad-spectrum (non-detect THC) is the safe choice.

How to actually give a cat CBD

1. Mix into wet food. Easiest; absorption slower but reliable. Works for most cats.
2. Onto a treat. A drop or two onto a Churu-style lickable treat. Cat sees treat, not medicine.
3. Empty gelatine capsule. Fill with the dropper dose, pop down the throat as you would a pill. Requires cooperation and skill; if your cat hates pills, don’t try.
4. Sublingual (drop into mouth) — only with willing cats. Faster onset but most cats find it stressful.

Don’t fight a cat to give CBD. If administration is causing stress, the CBD is working against itself.

When to talk to your vet (definitely)

• If your cat is on any prescription medication.
• If she is elderly (12+) or has known liver or kidney disease.
• If she is on a special diet or has GI sensitivity.
• If you see soft stool, excess sleepiness, or behaviour changes within the first week.
