My dear three year old cat Annie developed kidney disease and a very high calcium level, apparently an unusual combination. She had lost considerable weight and kidney function and my vet was very concerned. My vet referred her to UC Davis Vet School where the vets removed a large calcium stone from her ureter and took preventive measures with a stent so she will hopefully not develop another stone. The first visit to UC Davis with surgery and the stent was considered life saving. UC Davis researched and developed a unique diet for her because her situation is so specialized. They also researched and implemented a special steroid regimen for her, which, after two months so far, seems to be working successfully. Her overall regimen so far has resulted in weight gain her kidney and calcium values reverting to mid-range normal and I am so happy with her progress. Between my local vet and UC Davis, Annie's care has cost about $10,000 thus far. Thanks to PetPlan, a very high percentage of this has been covered, to my great relief. Thank you, PetPlan.
