Java our female F5 passed quickly a year and 6 months to the date due to kidney disease. She was 10 years old. Our male F4 Savannah Tau became sick on November 16th 2023. He was 11 years old. The vet said he had a UTI which was odd. Our savannahs have never been sick.They drank reverse osmosis water and have an alternating raw and Orijen dry diet. The vet put Tau on antibiotics and within days he was back at the vet looking very sick and not eating. He lost 10lbs in a weeks time. The other vet ran all the same tests but said he had Stage 2 Kidney disease. We did everything from subcutaneous fluids and full day IVs. He wasn't getting better. On Wednesday the night before Thanksgiving Tau crossed the rainbow bridge. I am still in disbelief how fast Kidney disease deteriorated our savannahs. I recall our breeder saying our savannahs should live 20 -25 years. I guess I was holding on to that idea that they would be with us for that long. I have tried to reach out to our breeder to see if this is a genetic thing but they are no longer breeding. their website and their number is disconnected. I appreciate any input to know if Kidney disease is prevalent in Savannahs? Thank you.
