Any type of animal that you take in as a pet will require time from you. Even cats, who are known for being independent, will requires you to pay attention to them. It’s still the same, cats will have special needs, for example, they like going out which means someone has to let the cat go in and out of the house. A way of avoiding this is by setting a cat door so you don’t have to be present at home all the time. Obviously, you have to make sure that the door is large enough for your cat, but small enough for dogs or small children, to avoid nasty surprises.
