What affects us affects cats
This is a photograph of an all-white Maine Coon cat with heterochromia iridum. In layperson’s language, this beautiful cat has odd-eye colour. And it is a classic case of odd-eye colour because one eye is yellow-gold and the other is blue. The reason why one eye is yellow-gold and the other blue is because …
The total amount of melanin (pigment) in the iris of the eye determines the range of eye colours in cats and in humans. The same principles apply to all animals with a similar eye anatomy. The pigment ‘melanin’ is produced by cells called melanocytes. The amount of pigment produced and the way that melanocytes …
Yes, cats’ eyes are more sensitive to light than those of humans. This is why they shine in the dark because of a reflective layer behind the retina which is called the tapetum lucidum – translation: “bright tapestry”. Humans do not have this layer and it allows the cat to capture light more effectively. …
The domestic cat has a tendency to be more active at night although they are not wholly nocturnal. They are described as crepuscular, meaning active at dawn and dusk when hunting is more successful. In general, when possible they tend to be active when it is dark and for this reason evolution has been …
The question in the title is probably meant to mean: do cats see objects under ultraviolet light only? For humans, ultraviolet light is beyond the visible spectrum and so we can’t see it. However, fundamentally, the anatomy of the cat’s eye is very similar to ours. Although they do see the world differently it …
Cats cannot see infrared light because it is not part of the visible spectrum. In this way cats are identical to humans except there MAY be a difference in that it is said that cats might be able to see ultraviolet light (UV). Both cats and humans can see light in the visible spectrum. …
This is a really nice picture of a cat, actually a cat with a big following on Twitter whose name is Curious Zelda, with wide open pupils because it was taken in low light conditions. You can click on it to see it in large format. There is often a confusion between pupils and …
This is a strange picture of a cat. Her eyes have what appears to be makeup on the outside edges so they look like somewhat like the eyes of the famous and grossly sad Cat Woman, Jocelyn Wildenstein. In other words this cat’s eyes have been made to look more feline. Either that or …
