Are You A Cat Lover?

Explanation
Cats are thought to be primarily responsible for the extinction of 87 species of birds. This is due to their hunting instincts and ability to catch and kill birds. Cats, especially feral ones, have had a significant impact on bird populations in many parts of the world. They are skilled predators and can have devastating effects on bird populations, particularly in areas where birds are not adapted to dealing with such predators. The high number of 87 species indicates the significant threat that cats pose to bird biodiversity.

Explanation
Cats were first domesticated in Ancient Egypt. The ancient Egyptians revered cats and considered them sacred animals. They believed that cats had protective qualities and worshipped a cat goddess named Bastet. Cats were kept in homes to ward off evil spirits and protect the household. The Egyptians also valued cats for their ability to catch and kill rodents, which helped protect their crops and food stores. The close association between cats and ancient Egyptian culture is well-documented through various artifacts and artwork depicting cats.

Explanation
The correct answer is 5500 BC. A 2016 study discovered that leopard cats were being domesticated independently in China around this time. This suggests that humans in China were actively involved in the process of taming and breeding leopard cats for domestication purposes during this period.

Explanation
The correct answer is 9,000 years. This is based on a 2017 study that confirmed that domestic cats are descendants of those first domesticated by farmers in the Near East around 9,000 years ago. This study provides evidence for the long history of human-cat interaction and the domestication of cats as pets.

Explanation
According to a 2007 study, cats are the second-most popular pet in the U.S. This suggests that there is a significant number of people in the U.S. who own cats and prefer them as pets. The popularity of cats in the U.S. could be attributed to various factors such as their independent nature, low maintenance requirements, and their ability to provide companionship to their owners.

Explanation
Carl Linnaeus is the correct answer because he was the Swedish scientist who first classified the domestic cat as Felis catus. Linnaeus is known as the father of modern taxonomy, and he developed the binomial nomenclature system that is still used to classify living organisms today. His work in categorizing and naming species has had a significant impact on the field of biology.

Explanation
There are two main theories about how cats were domesticated.

Explanation
The world record for the largest cat is 21 kg. This means that the cat weighed 21 kilograms, making it the heaviest cat ever recorded.

Explanation
Cats sleep for extended periods throughout the day, and the duration can vary. The range of 10 to 16 hours is considered normal for cats. This allows them to conserve energy and recharge for their active periods. Cats are known for their ability to sleep for long periods, and this range reflects their typical sleep patterns.

Explanation
Cats have a reproductive cycle known as estrus, or heat, which occurs approximately every two weeks. During this time, female cats become receptive to mating and may exhibit behaviors such as restlessness, increased vocalization, and rubbing against objects. This cycle continues until the cat becomes pregnant or until the hormonal changes subside. Therefore, the correct answer is two weeks.
