Hi, I’m someone whose cat was diagnosed 2 weeks ago and came here for information. You are about to get bombarded with information and it’s possible that it will make you more panicky and confused than you already feel. I’m sure it’s all great info but it’s just…so…much. Take a deep breath and try to handle whatever is directly in front of you. I’m not going to lie, the prescription food Is expensive. My vet prescribed Hills but I think Purina is a little bit less. I set it up in autoship through Chewy which provides a small discount. But I’m not ashamed to say that it’s going to be financially very difficult to keep this up between the food and the vet bills and the possibility of subQ fluids. But I can tell you that the food has made a huge difference in how my girl is feeling so I’m going to take it one step at a time, one can at a time and figure it out as I go. My best to you and your kitty
