when your cat hiss does it hurt them
The mom cat is hissing at the kitten to establish dominance, protect her territory, or discipline the kitten for misbehaving. Hissing is a way for cats to communicate their boundaries and assert their authority.
Hissing means that the cat is scared and it is trying to defend its self so stay away if a cat starts to hiss and arch his/her back.
The mom cat may be hissing at her 4-month old kitten to establish boundaries, discipline the kitten, or protect her territory. Hissing is a way for the mom cat to communicate with her kitten and teach it proper behavior.
Obviously, it didn't agree with your cat!
very carefully
When a cat is spitting, it makes a sharp, hissing sound.
Your female cat may be hissing at your male cat due to territorial issues, fear, or stress. It is important to monitor their interactions and provide a safe and calm environment for both cats. Consulting with a veterinarian or animal behaviorist may help address the underlying cause of the hissing behavior.
One cat may suddenly start hissing at another cat due to territorial behavior, fear, or feeling threatened. It could also be a sign of aggression or discomfort in their environment.
If your cat is hissing at strangers you can't stop your cat from hissing at them. The only thing I can think of that would stop a cat from hissing at someone is letting a cat get to know a person long enough that the cat isn't afraid of the person, and will therefore get along with him/her.
Normally you would hear a hissing sound accompanied by your cat being angry
