Outdoor House For Cats

A friend had an outdoor house for his cats and he would let them go wherever they wanted. I thought that it was an interesting method of caring for cats although not altogether safe. Something else interesting that I learned from him was about cat's ability to see. It seems that cats are born blind with their eyelids sealed together. It normally takes about seven to ten days for their eyes to open, and when they finally do, they still can't see well. Cats are all born with bluish gray eyes to being with, and their iris begins changing colors as time goes by. Cats cannot distinguish as many details as humans can, but they are able to capture the smallest movement, even when this movement happens at a distance even in the dark. Obviously this is because they were designed to hunt at the night. Because of their shape and structure, a cats eyes are designed to capture all of the light possible, and it's eyes are able to see six times more then humans eyes can in the dark. Behind a cat's eye there is a special layer of cells, which is called tapetum lucidum in Latin. This layer serves as a mirror that reflects the light that comes into direct contact with the cats eyes. This is what makes the cats eyes look like they are shining when it's eyes come into direct contact with a bright light.

For many years it was thought that cats could only see in black and white, however, recent investigations have demonstrated that cats are able to distinguish between the colors red, blue and white. If you ever notice that your cats third eyelid is showing a lot, take your feline immediately to the veterinarian as this is usually an indicator that the cat is sick.
