Can pets eat coffee, tea and energy drinks?

Coffee, tea and energy drinks
Toxic — treat as an emergency
Dogs: Toxic · Cats: Toxic · Birds: Toxic

If this has already been eaten, ring your vet or an animal poison control line now rather than waiting for signs to appear — for several of these the window in which treatment works closes before the animal looks unwell. Do not try to make the animal sick at home: home emetics are dangerous for corrosive and petroleum substances and for an animal already showing signs, and salt-based ones have themselves proved fatal.

By animal

Animal Verdict Why
Dogs Toxic Same class of compound as chocolate, and more concentrated in coffee grounds or a caffeine tablet.
Cats Toxic Same.
Birds Toxic Same.

What it actually does

Caffeine is a methylxanthine like theobromine and does the same things — cardiac stimulation, hyperactivity, tremors, seizures — but faster and at lower doses. A licked-up splash of coffee is rarely a problem; eaten coffee grounds, used or unused, tea bags, or caffeine supplement tablets are a real one, because the concentration is far higher than in a drink.

No reliable dose threshold has been published for this. Anything presenting a specific safe amount is extrapolating.

Body weight decides almost everything here, so what is trivial for a 40 kg dog can matter for a 4 kg one, and a bird is smaller again. Where a real published threshold exists this page gives it; where none does, it says so rather than inventing one.
