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]
Cat Because cats were venerated in ancient Egypt, they were commonly believed to have been domesticated there,[12] but there may have been instances of domestication as early as the Neolithic from around 9,500 years ago (7500 BC).[13] A genetic study in 2007[14] concluded that all domestic cats are descended from Near Eastern wildcats, having diverged around 8000 BC in the Middle East.[12][15] A 2016 study found that leopard cats were undergoing domestication independently in China around 5500 BC, though this line of partially domesticated cats leaves no trace in the domesticated populations of today.[16][17] A 2017 study confirmed that domestic cats are descendants of those first domesticated by farmers in the Near East around 9,000 years ago.[18][19]
