Pectus Excavatum is a condition in which the cat’s breastbone sinks into its chest.  In severe cases, the condition causes a deep dent in the middle of the chest. The sunken breastbone can often be noticed soon after birth, but it usually worsens during the feline’s adolescence. The condition is also more common in males than in females. Severe cases can affect the function of heart and lungs while surgery can correct Pectus Excavatum.

Since these cats can be out-crossed, they’re more likely to suffer from certain health conditions including hypertrophic cardiomyopathy (thickened heart), polycystic kidney disease (fluid-filled cysts), and hip dysplasia (ill-fitting bones).
