Can Siamese cats go blind?

Yes, Siamese cats can go blind, though not all of them will. They are genetically predisposed to certain eye issues because of how their genes affect the development of their retinas and optic nerves. Some Siamese cats are born with crossed eyes (strabismus) or involuntary eye movement (nystagmus), which doesn’t usually lead to blindness but may affect vision clarity.
However, they can still develop age-related blindness, glaucoma, progressive retinal atrophy (PRA), or other conditions that impact eye health in many other cats, too. Regular vet checkups and keeping an eye out (literally) for signs such as cloudiness, bumping into things, or changes in behavior can help catch vision problems early.
