What is a one-sentence summary of the following article?
It can be difficult to tell whether a cat is truly lost, or if it is allowed to venture outside its home. The cat may also be a stray with no home to return to. In general, if a cat seems healthy and calm, you may want to leave him alone. If they seem malnourished, injured, or afraid, they may be either a stray or a lost pet. If the cat is wearing a collar or tags, they definitely belong to someone. It never hurts to contact the owner. The first step in rescuing a lost cat is to get it into your custody. In order to do this, you must first approach the cat slowly and with caution. You do not want to startle it, and you also don’t want to get hurt. As you approach the animal, speak to them in a calm soothing voice. Kittens and cats tend react well to calm words. You may also try clicking, meowing, or saying “here, kitty kitty.” Using food to coax the animal toward you can be a safe and effective way to bring them close. Be sure to use food that a cat likes, such as canned cat food, tuna, cheese, or milk. Generally speaking, cats do not like to be held or restrained, so it is a good idea for stray cats to be confined somewhere safe. You can try placing the cat inside a pet carrier, a secure cardboard box (with air holes), a small room in your home, or, briefly, in your car, as long as your car is well ventilated and it the temperature isn’t too hot. If you come into contact with a wild or feral cat that you do not feel comfortable restraining, contact your local animal control agency. Never put yourself in danger trying to capture an aggressive cat. In rural areas, you may call the police instead.

Summary:
Look for signs that the cat is lost. Approach slowly. Speak in a calm voice. Use food to coax the animal to you. Confine the cat safely. Contact the authorities.
