A digitigrade animal is one that stands or walks with its toes (phalanges) on the ground, and the rest of its foot lifted. Digitigrades include birds (what many see as bird's knees are actually ankles), cats, dogs, and many other mammals, but not plantigrades (such as humans) or unguligrades (such as horses). Digitigrades generally move more ...
Cats are digitigrades, which means that they walk on their toes, just like dogs. The advantage of this is that cats (and other digitigrades) are more agile than other animals. Most animals have ground reaction forces (GRFs) at around two to three times their body weight per limb. But digitigrades have a higher GRF than other animals due to the ...
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.

The resting human body generates about two-thirds of its heat through metabolism in internal organs in the thorax and abdomen, as well as in the brain. The brain generates about 16% of the total heat produced by the body. [8] Heat loss is a major threat to smaller creatures, as they have a larger ratio of surface area to volume.
They are also produced by many aphids, in which they are sex pheromones. [1] Nepetalactones are cat attractants, and cause the behavioral effects that catnip induces in domestic cats. However, they affect visibly only about two thirds of adult cats. They produce similar behavioral effects in many other felids, especially in lions and jaguars. [2]
Florkiewicz explained that domesticated cats are typically more socially tolerant than their wildcat counterparts because of the way they live in proximity to humans, so the researchers were ...
The Manx cat (/ ˈ m æ ŋ k s /, in earlier times often spelled Manks) is a breed of domestic cat (Felis catus) originating on the Isle of Man, with a mutation that shortens the tail. Many Manx have a small stub of a tail, but Manx cats are best known as being entirely tailless; this is the most distinguishing characteristic of the breed ...
