In the 1930s, two Russian biologists discovered that color change in Siamese kittens depend on their body temperature. Siamese cats carry albino genes that work only when the body temperature is above 98° F. If these kittens are left in a very warm room, their points won’t darken and they will stay a creamy white.
Interesting :)
The average lifespan of an outdoor-only (feral and non-feral) is about 3 years; an indoor-only cat can live 16 years and longer. Some cats have been documented to have a longevity of 34 years.
