Most cat breeds do have eyelashes. They are usually not as dark and as long as humans’, and this is the most likely reason why many of you won’t notice them immediately.
Eyelashes serve as cats eyes’ protectors. Still, since cats also have their fur and whiskers that protect them from dirt and humidity, their eyelashes are not the only protection for their eyes.
You should keep the area around your cat’s eyes clean. If you notice hairs on your cat’s eyelids seem too long, you shouldn't trim it on your own. Rather, consult your vet for advice; He will pluck your cat’s eyelashes if necessary.
