Individual variation in the age of eye‐opening was studied in 158 kittens. The abiotic and the biotic environments affected eye‐opening. Eyes opened earlier in total darkness than in light, and earlier in kittens of young mothers than those of older mothers. Female kittens tended to open their eyes earlier than males, and a paternity effect appeared.
