If your cat is visibly angry, you will need to give her some time before you try to approach her and apologize; approaching too soon may result in getting scratched. Try not to wait too long to apologize, however; instead, approach the cat as soon as she appears calmer. You can also approach a frightened cat, but do so with caution. Refer to the section in this article on reading your cat's body language to learn how to determine your cat's mood.  If your cat keeps running away from you, consider leaving behind a small treat in a place she can find. This will let her know that you are sorry and still care about her. A frightened cat should be approached with care. Always give a frightened cat room to escape. She may actually need comfort and reassurance, especially if there was a loud, sudden sound. At the same time, however, she may want to be alone, which is why leaving an escape route is so important. A frightened, cornered cat may quickly turn aggressive. What did you do to make your cat so mad at you? Did you make fun of her? Step on her tail? Or did you take her spot on the couch? Knowing what you did wrong will help you decide how to approach your cat. It will also help you decide how to go about apologizing to him or her. Here are some examples of what you might have done to offend your cat and what you could do to show you're sorry:  If you offended your cat by making fun of her, you will probably have to offer some treats and praise. If you accidentally stepped on your cat's tail or startled her by dropping a pot, a simple cuddle may be all that is needed. If you took your cat's favorite spot on the couch, consider vacating the spot and giving your cat a treat. If your cat runs away from you, she may be still be angry, upset, or frightened. Do not chase after your cat. Instead, try again a few minutes later. This will reassure your cat that you won't do anything to further harm or annoy her. Having a cat treat ready may also reassure your cat. Tell her "I'm sorry." You may even use your cat's name....
