[Left: Domino rocking her body cast. Top right: before (top) and after xrays of her sternum. Bottom right: during surgery, using a pen to show the depth of the defect where her sternum was growing ‘in’ rather than ‘out’.]

Domino was a kitten I fostered who had a severe case of pectus exavatum, a condition where the sternum doesn’t grow correctly and instead damages the lungs. She stayed with me for months during her recovery and I became extremely fond of her.
