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 Perhaps the best known element of cats' hunting behavior, which is commonly misunderstood and often appalls cat owners because it looks like torture, is that cats often appear to "play" with prey by releasing it after capture. This behavior is due to an instinctive imperative to ensure that the prey is weak enough to be killed without endangering the cat.[174] This behavior is referred to in the idiom "cat-and-mouse game" or simply "cat and mouse".
