Short answer

Call your vet immediately — nicotine acts fast and even a small drop can be toxic to a cat. Do not try to induce vomiting unless your vet explicitly tells you to over the phone. Wipe her mouth gently with a damp cloth to remove any residue, and confine her to a carrier or small room where you can watch for tremors, drooling, or wobbliness. Bring the vape bottle with you to the clinic so the vet can see the nicotine concentration. Signs like excitement or vomiting can start within 15 minutes, so do not wait to see if she seems fine; go now.

What that drop does to a 5 kg cat

Vape juice nicotine concentrations vary wildly—even a 'small' drop from a 50 mg/mL bottle delivers about 1 mg, which is a toxic dose for your cat's weight. The liquid's viscosity means it coats the mouth thoroughly, unlike a solid they might spit out. Propylene glycol in the juice also enhances nicotine absorption compared to smoke or gum.

Since this happened 10 minutes ago, the nicotine is already circulating. At this point, preventing further absorption is more urgent than inducing vomiting (which risks aspiration if they're already neurologically impaired). Focus on limiting the toxin's spread.

The deceptive calm before symptoms

Some cats show no signs for 20–30 minutes, then deteriorate abruptly. Early agitation (pacing, excessive grooming) often precedes visible tremors. Check gum color—pale or bright pink gums can indicate blood pressure changes before other symptoms appear.

Their small size means nicotine saturates their system faster than in dogs. Watch for subtle signs like ear flicking or tail-jerking—these minor muscle movements often precede full-body tremors. Confine them now to prevent injury if seizures start.

Why vape juice differs from other nicotine forms

Liquid nicotine skips the slow release of patches or gum—it's immediately available for absorption. The flavored carriers (like fruit or dessert compounds) also encourage cats to lick more eagerly than they would bitter tobacco. Even 'nicotine-free' juices may contain trace amounts.

Vape juice often includes benzoic acid, which lowers saliva's pH and increases nicotine's potency. For a cat, this means the same amount hits harder and faster than cigarette tobacco would. The drop likely spread across their tongue's papillae, maximizing contact area.

Action steps while waiting for the vet

Use a wet cotton ball to dab—don't wipe aggressively—the tongue and roof of the mouth. This removes residual juice without pushing it deeper. Offer a shallow dish of water to dilute swallowed nicotine, but don't force it if they resist.

Note the vape juice's concentration (usually printed on the bottle in mg/mL) and estimated drop size. A grain-of-rice-sized drop from high-concentration juice requires more aggressive treatment than a larger drop from low-nicotine fluid. Keep them in a dim, quiet space to reduce neurological stimulation.
