Cats will use a range of different vocalisations to show their displeasure, often depending on the cat. These can range from low-pitched growls that sound like something a dog would make right up to hissing and even screeching. The latter is a loud, shrill meow that will make everyone who hears it jump and is a real warning sign of a big problem. It can also indicate an injury or that the cat is in pain in some way. The growl tends to be more of a warning sign that trouble is on the way unless something changes while hissing is a little like a boundary warning - you are infringing on my territory, go away! Cats also spit and the phrasing spitting mad does really apply with cats. Like screeching, this is one of the more extreme reactions that says they are either really angry or really frightened.
