Cat blue membrane is a thin film over the eyes that is usually present when cats are born. The main function of this blue film is to protect the cat's eyes. When the cat is born, the eyes are not fully developed, and the blue film prevents light from directly irritating the eyes. Generally speaking, a cat's blue membrane will begin to fade when the cat is about 2 to 3 months old.
As cats grow and develop, their eyes will gradually mature and the blue film will gradually disappear. This process is gradual and does not happen overnight. Breeders may notice that the cat's eye color gradually becomes clearer as the blue film fades.
It should be noted that each cat’s growth rate may be different, so the time it takes for the blue film to fade will also be different. Some cats may start to shed their blue membrane earlier or later, which is normal. If the breeder finds that the blue film has not completely faded when the cat is about 4 months old, there is no need to worry too much. As long as the cat’s eyes have no other abnormal symptoms, it is usually normal.
After the blue film fades, the cat’s eye color will become more colorful. Some cats’ eyes will appear beautiful green, amber or gold, etc. This is related to the cat’s breed and genetic factors.
Keepers should pay close attention to the cat’s changes before the blue devil fades away. As long as the cat’s eyes have no other abnormal symptoms, there is no need to worry too much. At the same time, after the blue film fades, the cat's eye color will become more beautiful and colorful, which is also a change in the cat's growth process. As a cat owner, if you notice any abnormal symptoms, you should seek medical attention promptly.
