To decide, you must have an idea what to expect from a cat. You must be familiar about the temperament of cats.
First of all, a domestic cat is a highly intelligent and fiercely independent creature. It can never be placed on a leash the way dogs are. Cats do things they want to do and when they want to do it. They will demand the things they want, such as food and play. And they will also make it clear when they want to be left alone. Thus, the owner of a cat cannot expect his pet to do “work” for him.
Different breeds of cats have different personalities. Some cats are quiet while others like to meow all the time. Can you tolerate a cat who meows almost every hour? Some cats are fussy and choosy about the food you give them while others will eat just about anything. Can you afford the kind of food that your cat prefers? Some cats don’t mind being surrounded and petted by strange people while others will wield their claws if they face a person they haven’t met before. Does your house accept many strangers or are you alone most of the time? And some cats love to climb and curl on the lap of their masters. But others prefer to be left alone, watching TV or listening to the radio. Are you a cat owner who likes to cuddle all the time?
You will know when your cat is trying to get your attention. It will endlessly meow at you or it will follow you around or it will rub its body against your leg. You will also know if your cat is comfortable or scared by lifting up your cat. If the body is loose, then your cat is relaxed. If the body is tight, then something is scaring the daylights out of it.
Cats like to sleep. And the specific personality and breed of the cat will determine where the cat chooses to sleep. Some like to be in secluded places where no one can disturb them. They like to lie in high cupboards and similar places. Other breeds of cats like to sleep in places where everyone is converging. These cats like to be noticed. So they sleep at the center of the foyer, in the middle of the stairs and even on the couch, especially when there are guests.
Cats like to sharpen their claws. It is their nature, similar to wild cats such as lions, tigers, panthers, and cheetahs. This may irritate the owner, especially if the cat chooses to sharpen its claws on the couch. The owner may consider giving the cat a scratching post. The cat can be taught to scratch its claws on this post.
