Last year when my bellowed kitty "Kocurik" (means little kitty boy) suffered Pancreatic Lipase he was not doing well. The doctors saved his life, but he was just not getting better. He behaved like a zombie, listless, and disoriented. I did some research and bingo!, the symptoms were consistent with lack of Potassium. I bought Renal K, which, in his case, doubled as a help in treating his kidney deficiency ( I hate to call it renal failure, seems so fatalistic) and he's going strong. He'd gained weight, he's playful and just a pride and joy to me, his mama. He's 14yrs old now and I am looking forward having him for a long time yet. Thank you, RENAL K!
