Common Health Problems

With a genetic history closely intertwined with the Siamese, Oriental shorthairs are predisposed to the same health problems as their pointed relatives. In general, however, the breed is considered healthy.

Health conditions observed in Oriental shorthairs include:

• Bladder stones: Cats can develop calcium oxalate or struvite stones. Symptoms include blood in the urine, pain during urination, slow urination, and difficulty urinating. Obstructions can also occur, which need emergency treatment.    
• Liver and kidney amyloidosis: This condition develops when amyloid, a misfolded protein, ends up in organs like the liver and kidneys, where it causes damage.
• Mast cell cancer: Mast cell tumors can occur in the intestine, skin, and spleen. Symptoms depend on where the cancer is located in the body.

• Crossed eyes: Known as convergent strabismus, crossed eyes in the Oriental shorthair is considered normal. Orientals might be born with one or both eyes crossed, but their vision shouldn’t be impacted. Seek veterinary attention if your cat’s eyes become crossed unexpectedly.
• Progressive retinal atrophy (PRA): This disease affects the retina and leads to blindness. Night vision usually deteriorates first.
