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").
Cats are generally more heat tolerant than dogs—after all, they love to seek sunny spots for a sunbath—but the dog days of summer are hot for your cat, too. Even though most kitties can ...
Furthermore, cats are superfecund; that is, a female may mate with more than one male when she is in heat, with the result that different kittens in a litter may have different fathers.

VCA Hospitals says cats are polyestrous, which means they go through estrus (heat) several times during their fertile season. A cat’s fertile season actually depends on where they live!
Because most of the preferred "domestic traits" are neotenous, or juvenile traits that persist in the adult, kneading may be a relic juvenile behavior retained in adult domestic cats.

Cats often chirp as a greeting to humans or other animals, though this could even sound like a peep or a trill. If your cat is giving you a greeting, it's bound to be pretty obvious!
Past research has highlighted the importance of a male's scent to females, such that smell was rated significantly more important for women than men. Furthermore, smell and body odour were rated as the most important physical factor for females, compared to looks for males. [60] Further studies have aimed to understand these sex differences.
If so, consider it a sign of love. One of the many strange things that cats do that are actually quite normal, licking you is their way of showing affection. Cats groom each other to form bonds ...
