- Bacterial, viral, or fungal infections can affect a cat's eye. Conjunctivitis, commonly known as "pink eye," is a frequent eye infection in cats. It can be caused by a variety of factors, including poor hygiene, exposure to other sick animals, or a weakened immune system.
- Symptoms: Along with squinting, there may be a yellow or greenish discharge, excessive tearing, and the eye may appear cloudy or have a different color than normal.
Glaucoma
- This is a more serious condition. Glaucoma occurs when there is increased pressure within the eye. It can be caused by various factors, including genetic predisposition or an underlying eye disease.
- Symptoms: In addition to squinting, the cat may seem in pain, the eye may be bulging, and there could be a loss of vision over time.
Cataracts
- Cataracts are the clouding of the lens in the eye. While they are more common in older cats, they can also occur due to certain diseases or genetic factors.
- Symptoms: The affected eye may appear cloudy or bluish - white, and the cat may start squinting as its vision becomes impaired.
