A domestic cat companion’s eyes are expressive. There are probably five basic eye configurations: Wide-open pupil i.e. a dilated pupil with wide-open eyes Narrowed eyes with a narrow slit of a pupil Half-closed eyes with the pupil in a relaxed mid-range position Closed eyes Stare Background The pupil is the aperture of the eye …
Well, the truth of the matter is that domestic cats’ eyes don’t only glow green in the dark. You will see a range of colours from green, yellow-green (cyan), orange and a reddish colour. We know the reason why domestic cats have glow-in-the-dark eyes. It’s because there’s a reflective layer behind the retina of …
