![]() Watching a cat fall from a distance is a living lesson in the principle of the conservation of angular momentum. Cats and figure skaters have a lot in commonĪt least when it comes to landing on their feet after a fall, that is. The difference between ours and theirs is that theirs is on the inside, close to the opening of the vagina - in just the right place for those barbs to really hurt! Get more kitty TMI here.Ĩ. Like all mammals, female cats do have a clitoris. Learn more about heartworms and cats here. Heartworm-associated respiratory disease is often misdiagnosed as asthma or allergic bronchitis. Although they don’t survive as well in cats as they do in dogs, the larvae grow inside the lungs and cause severe, chronic problems. Find out what else to expect when your cat is expecting.Ĭats can get heartworms, too. If not, see your vet to make sure she’s all right. By the third week she should start eating again and begin gaining weight. ![]() What else is up with your cat’s teeth? Find out here.įor the first two weeks of a cat’s pregnancy, she may eat less than usual because she’s feeling nauseous. When all is said and done, adult cats have 30 teeth. Between the ages of three and four months, the adult teeth come in. A set of 26 "baby teeth" comes in between the ages of two and four weeks. Like humans, cats have two different sets of teeth. A kitten’s age can be determined by her teeth The whiskers on the back of your cat’s forelegs, and to a lesser extent, those on her chin and the sides of her nose, are crucial for that purpose. When cats catch their prey, whether that prey is a mouse or their favorite feather toy, they need some way to sense that their prey is in the proper position for the fatal bite. Want to know more about cat eyes? Check out this article. Because cats have more rods and fewer cones in the back of their eyes than we do, their eyes are geared to detect movement and operate in low light and they don’t perceive details like leaves on trees or writing in books in the way that we do. The retina has two types of receptors: rods, which detect light, and cones, which detect color. There is no way to predict or force an X chromosome to inactivate at a certain point in development.ĭo you have a calico? Looking for a great name? Check out this article Naming Your Calico Cat: Name Ideas for Calico Cats.In the back of the eye is an area called the retina, where images and light are transmitted to the brain. Breeding an orange cat to a black cat may increase the chances, but it all depends on whether the kitten is female and at what stage during development the X-chromosome becomes inactive. It is difficult to breed specifically for calico or tortoiseshell cats. Males can be calico or tortoiseshell only if they are born with 2 X-chromosomes and a Y (XXY), allowing one X to be inactivated. Whatever color gene is present on this X chromosome will determine the color of the cat. Males have only one X chromosome, and it is never inactivated. Since X chromosomes inactivate at various times in each individual cat, color patches vary. If both X-chromosomes carry the same color gene, then the calico pattern will not appear. The same is true if the functioning X chromosome has the black gene. In calicos, if the X-chromosome that is left functioning carries the orange gene, then all the cells descended from it will result in an orange color. ![]() When this happens, all the cells descended from the activated X chromosome will have the same characteristics, including coat color. If two X chromosomes are present, which determines female sex, one X chromosome will become inactivated at some point in fetal development. This is especially true for the X chromosome. Gene Inactivationįor the sex chromosomes, there is a battle for power. ![]() Each time a cell divides, it passes on its genetic material. White coat color is associated with a completely separate gene.Īt conception, the kitten is a one-celled organism, which divides until there are millions of cells that make up the final kitten. In calicos and tortoiseshells, one X has the black gene the other X has the orange gene. Within the X chromosome is a gene for coat color. Within every chromosome there are thousands of different genes.Įvery female cat receives one X chromosome from her mother and one X chromosome from her father, while a male receives one X chromosome from his mother and one Y chromosome from his father. Every cat has 38 pairs of chromosomes half of the pairs are from the mother, the other half is from the father. Calico cats, with their orange, black and white coloration, are almost always female. ![]()
