Sparse hair on the British Shorthair's eyes is a normal phenomenon, and all cats are like this. If there are no other local symptoms, don't worry. If there are other symptoms, it may be a skin disease, which requires timely treatment. Generally, cat moss can also cause sparse hair or even hair loss, and local redness, dandruff, scabs, etc. can be sprayed on cats to treat skin diseases and wait until the hair grows back.
