Why does my cat hiss at me? Most often cats will start hissing at you because they are annoyed and are trying to tell you to back off. However, a hissing cat could also be telling you that they are in pain and need your help. So if you’re petting them or lifting them when the hissing sound starts, check to see if they have any signs of injury.

Why Is My Cat Hissing at Me? Your cat might hiss at you because they’re annoyed with you. They may not want to be petted right then, or it may be because you’re trying to pick them up when they don’t want you to. This type of hissing is also common if you have small children at home who don’t know when to leave the cat alone.
