Throughout life we learn something new and complement that knowledge. When I, 7 years ago, rescued from the streets and adopted a sick cat, I knew almost nothing about those wonderful critters, because before that I have had only dogs. I had a great desire to learn something, and since then I've read dozens of books, hundreds and hundreds of tips for various veterinarians, as well as thousands and thousands of experiences from other cat lovers. I even interested in the psychology of cats. The desire for more knowledge has not subsided and day after day I am expanding my skills and knowledge. Some of my knowledge I will try to carry over into this lengthy article, the knowledge will be gathered in one place, all the important things that most often trouble cat owners or people who for the first time met with cats.
