Plain-English summary
A male cat had a seizure at a humane society and was later diagnosed with primary hypoparathyroidism, a condition that affects calcium levels in the body. To treat this, the cat received calcium and vitamin D3 supplements, including injections of calcium gluconate. Unfortunately, a week after the injections, the cat developed firm lumps under the skin where the shots were given, which later became crusty and left scars. While the exact cause of these lumps wasn't confirmed, it is believed they were a reaction to the calcium injections.

Abstract
An adult male cat presented to the Ontario Veterinary College after having a seizure at the humane society. The cat was diagnosed with primary hypoparathyroidism and was treated with calcium and vitamin D3 supplementation. Calcium supplementation included subcutaneous (SC) administration of diluted calcium gluconate according to protocols described in recent literature. Seven days after SC calcium administration, firm SC masses developed in the intrascapular area where the injections were given and in the dependent axillary area. These areas became raised, formed crusts, necrosed, and left scars. Although not histopathologically confirmed, the author postulates that this was a direct reaction to SC calcium gluconate administration.
