eye, produces the watery portion of tears. The nasolacrimal duct
system allows tears to drain from each eye into the nose.
Disorders of these structures can lead to either eyes that water
excessively or dry eyes. They may be congenital (present at
birth) or caused by infection, foreign objects in the eye, or

common in cats as they are in dogs. However, a few disorders
occasionally are seen in this species. Blockage of the Nasal

overflow of tears due to an obstruction of the nasal duct called
epiphora. This is more common in Persian and Himalayan breeds.
In most cases, there is no reason for concern when this occurs,
as it does not lead to any medical problems. However, if

Inflammation of the tear sac is rare in c
