Health Predispositions Comparison

Compare genetic and constitutional health predispositions between the two breeds.

Cornish Rex

Patellar Luxation

Medium

A skeletal condition where the kneecap dislocates from its normal position. Dislocation is more likely during active play, causing lameness.

Gastrointestinal Issues

Medium

Many individuals have a sensitive digestive system, prone to diarrhea and vomiting from dietary changes or low-quality food.

Hypothermia Risk

Low

Their thin coat makes temperature regulation difficult, creating a risk of hypothermia in cold environments. Room temperature management and warmth are important.

Siamese

Amyloidosis

High

A disease where abnormal protein (amyloid) accumulates in organs. In Siamese cats, it particularly affects the liver and can lead to liver failure.

Feline Asthma

High

Siamese cats have a higher incidence of asthma. Allergens and stress can trigger coughing and breathing difficulties.

Convergent Strabismus (Crossed Eyes)

Low

A genetic eye condition in Siamese where both eyes turn inward. The effect on vision is usually mild and rarely impacts daily life.

Megaesophagus

Medium

A condition where esophageal motility decreases, preventing food from reaching the stomach normally. Regurgitation after eating is the main symptom.
