Progressive Retinal Atrophy or PRA-b is a genetic condition affecting the eyes. It causes a type of blindness resulting in the destruction of the cells responsible for detecting light. Typically, this disease afflicts kittens at the age of 7 weeks until slowly they become blind around 2 years of age.
Cats that are affected before going blind tend to have a harder time seeing at night and seem to have more dilated pupils. Otherwise they can lead a relatively normal life and quickly learn to navigate their surroundings.
Cats that carrier the gene are unaffected but if bred to another carrier or cat affected by PRA-b WILL pass it on to their offspring.
Luckily there is a genetic DNA test that can identify this genetic condition. Responsible breeders will have their cats tested for this condition and readily provide test results.
Please view each individual cat's page for test results
