Eating grass is a feline instinct that reaches back to all cats' ancestors. It improves digestion and induces regurgitation to cleanse the stomach of fur, feathers, and bones from the prey.

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.
