What is a fatal side effect of cisplatin in cats?

Cisplatin is a chemotherapy drug used in veterinary medicine, particularly for the treatment of certain tumors in cats and other animals. One of its well-documented and severe side effects is nephrotoxicity, which significantly impacts renal function. Cats are particularly sensitive to this aspect of cisplatin, leading to the potential for acute kidney injury and renal failure.

While pulmonary edema can occur due to other causes or medications, it is not a primary or fatal side effect specifically linked to cisplatin in cats. The other listed options, such as gastrointestinal hemorrhage or bone marrow suppression, may occur but are not as characteristic or fatal in the context of cisplatin administration in felines as nephrotoxicity. Therefore, understanding the nephrotoxic potential of cisplatin is crucial for safe administration and monitoring when treating feline patients.
