Cats greeting by rubbing against each other; the upright "question mark shape" tails indicate happiness or friendship. Cats rely strongly on body language to communicate. A cat may rub against an object or lick a person. Much of a cat's body language is through its tail, ears, head position, and back posture.
Among domestic cats, males are more likely to fight than females. [122] Among feral cats, the most common reason for cat fighting is competition between two males to mate with a female. In such cases, most fights are won by the heavier male. [123] Another common reason for fighting in domestic cats is the difficulty of establishing territories ...
The Felinae, on the other hand, comprises mostly small to medium-sized cats, including domestic cats, but also some larger cats such as the cougar and cheetah. [ 7 ] A 2010 study published in Molecular Phylogenetics and Evolution has given insight into the exact evolutionary relationships of the big cats. [ 8 ]
They rarely meow to communicate with fellow cats or other animals. Cats can socialize with each other and are known to form "social ladders," where a dominant cat is leading a few lesser cats. This is common in multi-cat households. Cats can use a range of communication methods, including vocal, visual, tactile and olfactory communication.
The first cats emerged during the Oligocene about , with the appearance of Proailurus and Pseudaelurus. The latter species complex was ancestral to two main lines of felids: the cats in the extant subfamilies and a group of extinct "saber-tooth" felids of the subfamily Machairodontinae , which range from the type genus Machairodus of the late ...
In the summer of 1960, the BSCS convened an intensive summer writing conference in Boulder, at which three new high school biology textbooks were developed. The three versions were: Blue, a molecular biology approach; Green, an ecology approach; and Yellow, a cellular biology approach. These three versions, and their corresponding newly ...
Cats are able to tolerate quite high temperatures: Humans generally start to feel uncomfortable when their skin temperature passes about 38 °C (100 °F), but cats show no discomfort until their skin reaches around 52 °C (126 °F), [27]: 46 and can tolerate temperatures of up to 56 °C (133 °F) if they have access to water.
The tail seems to help but cats without a tail also have this ability, since a cat mostly turns by moving its legs and twisting its spine in a certain sequence. [2] While cats provide the most famous example of this reflex, they are not the only animal known to have a mid-air righting capability.
