Aspirin, a well-known non-steroidal anti-inflammatory (NSAID), is commonly used for pain relief, fever reduction, and clot prevention. While you may be tempted to give it to pets with similar symptoms, aspirin is toxic to our furry companions and can potentially cause a life-threatening illness.

How is aspirin toxic to dogs and cats?

When aspirin is ingested by a dog or cat, it blocks certain enzymes from maintaining normal stomach and intestinal functions, blood flow to the kidney, and allowing platelets to form a clot. This can lead to the following symptoms:

  • nausea and diarrhea
  • stomach and intestine ulcers and bleeding
  • kidney injury or failure
  • reduced clotting ability

Cats are especially sensitive to aspirin poisoning because it stays in their system for a longer period of time. All NSAIDs, including aspirin, Tylenol, and Ibuprofen, can negatively interact with other medications and amplify the harmful effects.
