Hissing is one of the ways cats communicate with other cats, people and other animals. The meaning behind the hiss often has a lot to do with the current situation and surroundings. For instance, if your cat is playing with you and suddenly hisses at you then she could be signaling that she’s done playing. If your cat hisses at you when you’re trying to pick her up, then don’t pick her up as the hiss is a warning. Cats may also hiss to show possession. Your cat could hiss at you to make you step away from her food or toys or she could hiss at another animal or person to get them to stay away from you her owner. If you cat is excessively hissing, then she may be ill or uncomfortable. Talk with your veterinarian Rochester, NY to find out what the constant hissing is about.
