Despite the cat's unbeatable night vision, a cat's daytime vision actually does not differ all that much from that of a human! As a result, cats are primarily nocturnal hunters looking for small rodents and birds. The average house cat sleeps about 18 hours a day and usually spends its waking time searching for food. Although wild cats are solitary animals, the house cat is known to enjoy the attention of humans and other animals and often even gets along well with some dogs. 8 x 2 x 6.25 cm
