Congenital Feline Hypothyroidism With Partially Erupted Adult Dentition in a 10-Month-Old Male Neutered Domestic Shorthair Cat: A Case Report

Abstract

Congenital feline hypothyroidism was diagnosed in a 10-month-old kitten. The kitten appeared to have disproportionate dwarfism, with the clinical signs of incompletely erupted permanent dentition covered by thickened gingival tissue, short stature, a broad, flattened face, short neck, pendulous abdomen, kitten-like hair coat, and goiter. Hypothyroidism was confirmed with baseline T₄, freeT₄, and thyroid-stimulating hormone testing. The kitten was treated with thyroid hormone supplementation and monitored. The kitten appeared clinically like a normal healthy cat at 22 months of age on thyroid supplementation.
