Why is my cat closing one eye?
- Eye injury or trauma
Looking at how affectionate cats could be especially when they are comfortable around their favorite person or pet, one can easily conclude that such an attitude is in their nature. That is not true though because they are very territorial and would engage in fights with any other animal they deem as a competitor.
Sometimes, this fight may not end well for them, and may sustain an injury, if this injury is sustained on their eye, they may close the affected eye due to discomfort.
- Something stuck in their eyes
While playing with other pets or their kittens, some particles from their environment like sand, dust, chemicals, wind, or grass seeds may enter the eyes of your cat which could cause irritation or itchiness.
They may close one eye or squint while trying to deal with the discomfort caused by the irritants.
- Eye ulcer
An eye ulcer is also known as a corneal ulcer is an eye condition that is common in cats. An eye ulcer will appear as a wound on the eye of your cat which could cause itchiness, discharge, or redness.
Most cats in the bid to alleviate the discomfort caused by this infection will rub their eyes with their paw or close one of the eyes. So if you see your cat opening just an eye, it is likely suffering from an eye ulcer.
- Allergic reaction
Your cat may want to munch on anything it sets its eye on, do not encourage such a habit. They may even want to have a bite of whatever you are eating, do not indulge them. This is because certain foods could impact negatively on their health which could lead to allergic reactions. Although allergic reactions can come in different forms, they can also come in the form of swelling around the eyes which could cause discomfort to your cat. Your cat may be closing one eye to assuage the pain.
Feline glaucoma is another possible eye condition that may cause your cat to close an eye. Glaucoma is a condition of the eye where it becomes difficult for the aqueous humor I.e. the watery liquid found in the frontal part of the eye, right behind the lens to drain normally.
