Why do cats die when they eat paracetamol?

Answer 1

Giving drugs meant for humans to a cat can be fatal. Even a supposed small dose could easily kill a cat, as their metabolisms are completely different to ours. Paracetamol, even tiny doses, damages the red blood cells and the liver and veterinary treatment needs to be taken immediately if a cat has ingested human medication.

A cat poisoned by paracetamol may seem nauseous or vomit. In the first few hours, an affected cat's breathing may become faster and more laboured. Her tongue may go blue and her heart beat faster- these are effects of reduced oxygen carrying capacity of the blood. The cat may become depressed and lethargic. If the cat survives these early symptoms, over the next few days, she is likely to produce blood-stained urine, develop abdominal pain, and may become jaundiced (where the whites of the eyes become yellow). Seizures are possible, as is a lapse into a coma. Death can occur up to 6 days after the consumption of paracetamol.

It is said treating a cat for paracetamol poisoning is difficult, intensive and often ineffective.

If you believe your cat is unwell or in pain, a vet will be able to administer safe and effective treatment for your cat.

Answer 2

Cats lack a specific liver enzyme necessary to breakdown paracetamol effectively, leading to the accumulation of toxic byproducts that can cause severe damage to their red blood cells and liver, potentially resulting in organ failure and death. It is important to never give paracetamol to cats and to seek immediate veterinary care if ingestion is suspected.

Answer 3

Paracetamol is poisonous to cats. They lack the enzymes required to break it down and so methaemoglobin is formed in their red blood cells which inhibits oxygen transport.
