Cats have relatively few taste buds compared to humans. Owing to a mutation in an early cat ancestor, one of two genes necessary to taste sweetness may have been lost by the cat family. Their taste buds instead respond to amino acids, bitter tastes and acids. To aid with navigation and sensation, cats have dozens of movable vibrissae (whiskers) over their body, especially their face. These provide information on the width of gaps and on the location of objects in the dark, both by touching objects directly and by sensing air currents; they also trigger protective blink reflexes to protect the eyes from damage.
Health
In captivity, an average life expectancy for male indoor cats at birth is 12 to 14 years, with females usually living a year or two longer. However, there have been records of cats reaching into their 20s and 30s, with the oldest known cat, Creme Puff, dying at a verified age of 38. Having a cat neutered or spayed confers some health benefits, since castrated males cannot develop testicular cancer, spayed females cannot develop uterine or ovarian cancer, and both have a reduced risk of mammary cancer. The lifespan of feral cats is hard to determine accurately, although one study reported a median age of 4.7 years, with a range between 0 to 10 years.
