Johnson's Calm Eze Tabs

Fireworks night, a thunderstorm, or a long car journey tend to reveal which pets can shrug things off and which ones can't — and for the second group, the run-up to the event is usually worse for the owner than the event itself.

These are tablets built as a natural dietary supplement, enriched with amino acids, vitamins and minerals, rather than anything requiring a prescription. Johnson's describe them as helping to calm and soothe nervous and hyperactive dogs and cats, with particular mention of thunderstorms, fireworks and travel, and say they can also help with aggressive or territorial behaviour. The pack contains 36 tablets.

• 36 tablets
• Natural dietary supplement with amino acids, vitamins and minerals
• Aimed at nervous or hyperactive dogs and cats
• Suggested for thunderstorms, fireworks and travel
• Easy-to-use tablet form

On timing. Johnson's don't state how long before an event to give a tablet, or how many tablets make up a single dose — that detail is on the pack itself, so read it before firework night arrives rather than during it, and a pet whose reaction is severe or worsening needs a vet's input rather than a bigger dose.

Who it's for: owners of a dog or cat that struggles with specific stressful events — fireworks, storms, car journeys — who want a supplement to have ready rather than nothing at all.
