Every person who has cats at home would always be worried about one particular habit of cats. THis habit is nothing but spraying. Pet cats have the habit of spraying in the house itself. The smell of cat urine would be quite nasty. Moreover, if there are many cats at home, the smell would be too much to bear. This problem is seen more often in homes with male cats. There are many cat owners who go to the extent of even neutering male cats.
