Why is my senior cat not eating and acting lethargic for 2 days?

Updated On September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 16 years and 6 months old

My cat is 16 y/o, has little to no interest in food. Its been 2 days since his sudden appetite loss. He's acting lethargic as well. I'm scared and really don't want to lose him. Could he possibly just have "kitty flu" or something?

Hi, and thanks for your question. These signs could be compatible with an inflammation infection of the gastrointestinal system and surrounding organs (like pancreas and liver). A clinical examination at your local veterinarian is immediately essential to confirm these clinical suspicions and treat appropriately. Antibiotics and possibly further investigations (like abdominal imaging as ultrasound or radiographs) may be needed. Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further. If this answer was helpful please let us know, this will be used to improve our service!
