Final answer:
The most commonly reported adverse events in cats after administration of NSAIDs are related to the renal system and include renal failure, although GI bleeding and GI perforation are also significant risks.
Step-by-step explanation:
The most commonly reported adverse events in cats after administration of NSAIDs are related to the renal system and include renal failure. This is because NSAIDs inhibit the production of prostaglandins, which are crucial for maintaining blood flow to the kidneys. High doses or long-term use of NSAIDs can lead to decreased prostaglandin production, which may result in reduced renal function or even kidney damage. In addition to renal effects, NSAIDs can cause gastrointestinal issues such as GI bleeding and GI perforation. Therefore, it is important to monitor cats closely for any signs of gastrointestinal distress or changes in kidney function when they are on these medications.
