when do cats open their eyes after birth
Kitten For the first several weeks, kittens are unable to urinate or defecate without being stimulated by their mother.[5] They are also unable to regulate their body temperature for the first three weeks, so kittens born in temperatures less than 27 °C (81 °F) can die from hypothermia if their mother does not keep them warm.[6] The mother's milk is very important for the kittens' nutrition and proper growth. This milk transfers antibodies to the kittens, which helps protect them against infectious disease.[7] Newborn kittens are unable to produce concentrated urine, and so have a very high requirement for fluids.[8] Kittens open their eyes about seven to ten days after birth. At first, the retina is poorly developed and vision is poor. Kittens are not able to see as well as adult cats until about ten weeks after birth.[9]
Grumpy Cat Tardar Sauce was one of a litter of four kittens born to a calico mother and a father of an unknown breed at the home of her owner, Tabatha Bundesen.[6][7] The Bundesens say that Tardar Sauce's face appears grumpy because the feline has a form of dwarfism. She and her brother Pokey were born to normal parents with "a flat face, bubble eyes, and a short tail".[8] Tardar Sauce is undersized and has hind legs that "are a bit different".[2][4] Although she has a "grumpy" appearance and is called "Grumpy Cat", according to the Bundesens, 99% of the time she is a "normal kitty".[2][4][9]
