The muzzles of our feline friends, as well as the ones of other animals (rodents, dogs, seals), have long and thick whiskers. Animal whiskers, as they're commonly called, say a lot about their health.

A four-legged friend does not only represent great joy, but also constant issues. Even if you've got a trained cat that knows how to use the WC, you might occasionally find unpleasant surprises somewhere in the flat - the felines can do their dirty business near the litter as a protest, and other times they simply mark their territory using this method.

In nature, big cats first appeared in regions with cold climate. Their size has been influenced by evolution. The larger the cat, the less its heat loss. Modern big cats have occurred as a result of interspecific crossbreeding.
