The cause of the "cat gap" is disputed, but it may have been caused by changes in the climate (global cooling), changes in the habitat and environmental ecosystem, the increasingly hypercarnivorous trend of the cats (especially the nimravids), volcanic activity, evolutionary changes in dental morphology of the Canidae species present in North ...
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.
This has been interpreted as researchers as evidence for the hominids chewing predominantly with their back teeth. [13] In addition, P. boisei possesses the thickest enamel of any hominid specimens found. [11] Despite such large back teeth, the incisors and canines were smaller than other species from the time.

A 2021 study out of Japan showed how targeting genes can regrow teeth in animals. ... A sliver of what makes sharks so intriguing comes with their ability to regrow teeth. And while a group of ...
Oral disease is not a new problem for cats. A 2014 study examined the skulls of cats that died before 1960 and discovered the same feline dental diseases found in modern times. [4] This highlights that felines are predisposed to poor oral health, a trait which is likely due to their origins as a desert species and the typical diet they consume.
Natal and neonatal teeth are an anomaly that involves teeth erupting in a newborn infant's mouth earlier than usual. The incidence ranges from 1:2,000 to 1:3,500 births. Natal teeth are more frequent, approximately three times more common than neonatal teeth. Some authors reported a higher prevalence in females than males.

New, permanent teeth grow in the jaws, usually under or just behind the old tooth, from stem cells in the dental lamina. [5] Young animals typically have a full set of teeth when they hatch; there is no tooth change in the egg. Within days, tooth replacement begins, usually in the back of the jaw continuing forward like a wave.
