Plain-English summary
Two Ragdoll cats in Norway were found dead due to kidney disease, which was linked to oxalate-like nephrosis. Their relatives showed signs of urinary tract issues, including a kitten that died from urethral gravel. Eleven living Ragdoll cats, including relatives of the deceased, were tested for a genetic condition called primary hyperoxaluria, but none were found to have it. Five of these cats had kidney abnormalities, and one developed severe kidney disease nine months later. The exact cause of the kidney problems in this breed is still unclear.

Abstract
Two unrelated Ragdoll cat mothers in Norway were found dead from renal disease. The histopathology was consistent with oxalate nephrosis with chronic or acute-on-chronic underlying kidney disease. Both cats had offspring and relatives with signs of urinary tract disease, including a kitten dead with urethral gravel. Eleven living Ragdoll cats, including nine relatives of the dead cats and the male father of a litter with similarly affected animals, were tested for primary hyperoxaluria (PH) type 1 and 2 by urine oxalate and liver enzyme analysis. Renal ultrasound revealed abnormalities in five living cats. One of these was azotaemic at the time of examination and developed terminal kidney disease 9 months later. A diagnosis of PH was excluded in 11 cats tested. The inheritance and aetiological background of the renal disease present in the breed remains unresolved at this point in time.
