Cats are highly territorial, and secretion of odors plays a major role in cat communication. The nose helps cats to identify territories, other cats and mates, to locate food, and has various other uses. [7] A cat's sense of smell is believed to be about fourteen times more sensitive than that of humans.
Cats have a larger olfactory epithelium than humans (about 20 cm 2), meaning that cats have a more acute sense of smell. [18] In fact, cats have an estimated 45 to 200 million odor-sensitive cells in their noses, whereas humans only have 10 million odor-sensitive cells (known as "olfactory receptor neurons", or "ORNs"). [19] [20] [21] Cats also ...
A male Amphimachairodus giganteus was one of the largest machairodonts. It dwarfs its modern relative, the common house cat, Felis catus. Based on mitochondrial DNA sequences extracted from fossils, machairodontines diverged from the ancestors of living cats around 20 million years ago, with the last surviving machairodont genera Homotherium and Smilodon estimated to have diverged from each ...
The urine of mature male cats in particular contains the amino acid known as felinine which is a precursor to 3-mercapto-3-methylbutan-1-ol (MMB), the sulfur-containing compound that gives cat urine its characteristically strong odor.
It’s a well-established fact that cats rule the Internet. From their toe beans to their tongue tips, netizens can’t seem to get enough of felines doing their furry thing, whether they’re ...

Ingestion of cat feces containing oocysts: This can occur through hand-to-mouth contact following gardening, cleaning a cat's litter box, contact with children's sandpits; the parasite can survive in the environment for months. [48] Ingestion of untreated, unfiltered water through direct consumption or utilization of water for food preparation ...
A cat pheromone is a chemical molecule, or compound, that is used by cats and other felids for communication. [1] These pheromones are produced and detected specifically by the body systems of cats and evoke certain behavioural responses. [1] [2] Cat pheromones are commonly released through the action of scent rubbing. [2]
