His chest looks normal to me. My husband says that he believes the protrusion is above the rib cage. Our vet took multiple x-rays. I suppose it could be a rib that is protruding, but wouldn't that have shown up in the x-ray? Vet described it as pectus excavation - mild form of the condition. Sternum caudally displaced from ribcage causing a "hole" effect. I am quoting from his health certificate.
We will look for a qualified surgeon. He also does not always use the litter pan. Could this be a symptom of his discomfort? It seemed to take him an extended time to urinate this morning when he did get in the litter pan while I was cleaning it. Our vet prescribed Metronidazole which we have been giving him.
