What drugs should not be given to cats? - briefly
Cats should never be given acetaminophen (Tylenol), ibuprofen, or aspirin, as these can cause severe toxicity or even death. Additionally, avoid administering any human medications or dog-specific drugs without veterinary approval.
What drugs should not be given to cats? - in detail
Cats have unique physiological and metabolic processes that make them particularly sensitive to certain medications, which can be highly toxic or even fatal if administered. One of the most dangerous drugs for cats is acetaminophen (commonly known as Tylenol). Even a small dose can cause severe liver damage and methemoglobinemia, a condition where the blood cannot carry oxygen effectively. Ibuprofen and other nonsteroidal anti-inflammatory drugs (NSAIDs) are also extremely harmful, as they can lead to gastrointestinal ulcers, kidney failure, and neurological issues. Aspirin, while sometimes used in very specific, controlled doses under veterinary supervision, is generally unsafe due to the risk of causing bleeding disorders and organ damage.
Another class of drugs to avoid includes antidepressants, particularly those containing selective serotonin reuptake inhibitors (SSRIs) like fluoxetine or sertraline. These can cause serotonin syndrome in cats, leading to agitation, tremors, and even seizures. Benzodiazepines, such as diazepam (Valium), can cause acute liver failure in some cats, despite being used safely in other species. Essential oils and herbal supplements, often considered natural remedies, can also be toxic; for example, tea tree oil can cause severe neurological and liver damage in cats.
Decongestants like pseudoephedrine, found in cold medications, are highly dangerous and can lead to elevated heart rate, high blood pressure, and seizures. Additionally, certain antibiotics, such as tetracyclines, can cause severe gastrointestinal distress and liver issues in cats. Topical medications designed for humans or other animals, especially those containing permethrin (commonly found in flea treatments for dogs), are extremely toxic to cats and can cause seizures, tremors, and death.
It is crucial to never administer any medication to a cat without explicit guidance from a veterinarian. Cats metabolize drugs differently from humans and dogs, and even medications considered safe for other species can have devastating effects on feline health. Always consult a professional to ensure the safety and well-being of your cat.
