My cat has been on Lasix for a few months - they've been increasing the dosage. His potassium levels have dropped a lot even though he's getting potassium powder 3 times daily. He is active and wants to eat - takes me into the kitchen and asks and even gets excited when I am opening the can of tuna. But then he sniffs it and walks away. It's been happening for several days now. I've force fed him a bit but he gets annoyed after a few bites. Has anyone else experienced this? Thanks so much!
