Plain-English summary
A 4-month-old male domestic shorthair cat was brought to the vet because he was lethargic, vomiting, had diarrhea, and was experiencing muscle tremors. Tests showed he had low calcium levels and high levels of certain hormones, leading to a diagnosis of vitamin D-dependent rickets type 2, a condition affecting bone health. The vet treated him with calcium and calcitriol (a form of vitamin D) supplements. Over the next 18 months, the cat improved and returned to normal health, eventually stopping the calcium supplements while maintaining healthy calcium levels on his own.

Abstract
Vitamin D-dependent rickets type 2 in a four-month-old cat A 4-month-old male domestic shorthair cat was examined because of lethargy, vomiting, diarrhea, muscle tremors, and mydriasis. Laboratory evaluation revealed hypocalcemia, hyperphosphatemia, and high intact parathormone and calcitriol concentrations. Findings were compatible with a diagnosis of vitamin D-dependent rickets type 2. Treatment consisted of oral administration of calcium and calcitriol supplements. During the subsequent 18 months, the cat remained clinically normal. Treatment with oral calcium supplements was eventually discontinued, and the cat was able to maintain serum calcium concentrations within reference limits.
