Update on our cat, Bud. He still had a bladder infection, but the vet has switched him to a gentler antibiotic and gave us some things to help boost his appetite. He also has an ear infection now. This is one sick cat. But, in principle we have everything we need to put him on the mend. Ironically, his blood work that checks for his continued renal failure suggests he's at worst holding steady and at best improving a little.
