Pet Medication Safety

Always Consult Your Vet

This calculator provides reference doses only. Many medications interact with other drugs, are contraindicated in certain conditions, or require different doses for puppies/kittens. Always confirm the dose and safety with your vet or a phone triage service before administration.

Cats Are Not Small Dogs

Cats lack certain liver enzymes and cannot metabolise many drugs that are safe for dogs. Aspirin, ibuprofen, paracetamol (acetaminophen), and many human medications are toxic to cats. Never give a cat any medication intended for dogs without explicit veterinary guidance.

Prescription vs OTC

Most effective pet medications are prescription-only in the UK and EU. Over-the-counter flea and worm treatments vary significantly in efficacy. Prescription spot-on treatments from the vet are typically more effective than supermarket alternatives.
