2. They are very well groomed.
Domestic cats spend a lot of time grooming themselves. If given the opportunity, they’ll also groom other cats or, even, other pets. Grooming maintains healthy skin by stimulating production of essential skin oils.
3. They’re live-in vermin exterminators.
They’ll also hunt and kill other rodents, lizards or bugs that get in the house. The hunting instinct is left over from cats’ ancient predatory past. In the past, the instinct helped your cat’s wild ancestors survive. Today, it helps keep your house pest free.
