It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears. Affected individuals are highly susceptible to life\u2010threatening infections due to the disruption of the skin's protective barrier. To date, IF and its genetic basis have not been described in domestic cats.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objectives<\/jats:title>\n                    <jats:p>To characterize the gross clinical, histopathological and genetic features of IF in two stray, random\u2010bred domestic short\u2010hair (DSH) littermates.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Animals<\/jats:title>\n                    <jats:p>Two deceased female neonatal DSH kittens, both exhibiting sparse hair and deep fissures exposing the underlying dermis.
