I haven't been on this forum in a few months. My cat Apollo has been doing great until this week. For some reason, he just wasn't acting himself and within a short couple of days, he went downhill fast. He stopped eating and drinking and he was weak. He has been at the vetst all day and through the night with an IV for fluids/electrolytes. He still is very sick. I went to see him tonight and brought him some things from home. What is the % or positive prognosis of a kitty recovering from ketoacidosis? It is possible that the insulin (Lantus) I've been using is not as effective. Does anyone know the expiration of this, if refridgerated and used? I love my Apollo and hope he will be o.k. Lisa
