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").
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. [167] The morula forms 124 hours after conception. At 148 hours, early blastocysts form. At 10–12 days, implantation occurs. [169]
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!

Cat urine, especially that of male cats, contains the putative cat pheromone 3-mercapto-3-methylbutan-1-ol (MMB), a compound that gives cat urine its typical odor. The MMB precursor felinine is synthesized in the urine from 3-methylbutanol-cysteinylglycine (3-MBCG) by the excreted peptidase cauxin .
There are some other pets that seem to cope even better with change than cats do, but felines are a good deal better than people. Fear of change seems to be wired into our brains to some degree.
Cats exceeded dogs in number as pets in the United States in 1985 for the first time, in part because the development of cat litter in the mid-20th century eliminated the unpleasantly powerful smell of cat urine. [9] A 2007 Gallup poll reported that men and women in the United States of America were equally likely to own a cat. [10]
