Cats may start to lose their sight for a variety of reasons, including old age. The change is often so gradual that many owners don't notice anything unusual, until the loss becomes total. Cats compensate for impaired vision by relying more on their remaining senses, especially smell. Older cats in particular, with their more relaxed approach to life, generally appear unfazed by failing sight.

How can I tell if my cat is blind?
Cats that bump into things may be losing their sight. Those that are blind in one eye may be startled by sudden movements on their blind side. If you are concerned about your cat's eyesight, arrange for an examination by your vet.

Adapting to blindness

• When talking to your pet, make your speech frequent and exaggerated.
• Blind cats are easily disorientated and must not be allowed to roam.
• Blind cats rely on scent and memory to find their way around, so keep food, furniture and litter trays in the same place.
• Highlight potential hazards, such as stair landings, with small amounts of lemon oil or potpourri.
• Don't leave obstacles in unexpected places.
• Make sure cats wear a quick release collar with their name, address and the phone number of a vet.
• Use a lead for walking outdoors in the garden. You can then observe what attracts the attention of your cat.
