My cat had surgery to remove a tumor from his abd.  When he came home he was doing extremely well.  Moving around and eating well.  I was given oral metacam doses to give him once a day for about a week.  At about a week and a half after his surgery he wasn’t eating, was very weak.  He could barely walk.  When I took him the the vet ER, his kidney labs were off the charts.     Updated   My cat died 2 days ago...
