Ate or licked it? Contact a vet now

Call a veterinary clinic straight away, day or night, even if your pet seems well: signs can take hours or even days to appear.

Say what was eaten or licked and when, and take the packaging with you.

Why it is dangerous to cats

Antifreeze, the coolant in a car, can contain ethylene glycol. In the body it turns into substances that damage the kidneys quickly and badly. It is enough for a cat to drink from a puddle under a car or in a garage, or to walk through one and lick the liquid off its paws and coat.

At first the cat can look as if it were drunk: it wobbles, vomits and drinks a lot. Later it may seem better, while the kidneys are being damaged. Time matters a great deal here: a vet can only help if the cat is brought in as early as possible.

If your cat may have licked antifreeze or got it on its paws, contact a vet or an emergency clinic straight away, even if it seems well. Take the packaging with you.

What to watch out for

  • The first signs, wobbliness, vomiting and thirst, can appear quickly.
  • The cat can seem to recover while the danger has not passed.
  • The kidneys are damaged within a short time, and later the cat may stop urinating.
  • A puddle under a car is dangerous even if the cat only wets its paws in it.
  • Keep antifreeze tightly closed, and clean up any spill straight away.

The forms it comes in

The same substance can turn up in different places.

  • Puddle under a car

    Dangerous

    Leaked coolant stays on the ground, and a cat can drink it or step in it.

  • Liquid on the paws or coat

    Dangerous

    The cat swallows it while grooming.
