Tonight my almost 3 year old daughter was having a temper tantrum because she forgot to kiss her grandma goodbye and I poured her milk instead of her daddy doing it....grrrr. So she screamed that scary, haven't-had-a-nap-all-day scream, and I was trying to calm her down so she didn't hurt herself and here comes "Super Gizmo" my 20 pound kitty, gets up on his hind legs and beats the crud out of my arm smacking and biting....he schocked us both and my daughter stopped screaming for half a second...when she starts back up he runs around the other side of my room to my husband and does the same thing to him all the while hissing in protest...he thought we were hurting my daughter and he was protecting her...I have never heard of this...I looked around a little and can't find anyone else who has witnessed this...he's done it before. A few weeks ago I stepped on my dogs tail sticking out from under the bed, he turned and growled at me and hear comes "Super Gizmo" who begins hissing and smacking the dog. It's touching that he wants to protect us...especially since he was given to us because his previous owners had children and they claimed he wasn't good with kids so they had to lock him in the basement. ...hmmmm
Every cat I've had would come running and seemed very concerned if any one made a loud noise. We could be yelling, crying or laughing and they would rush to see what are problem was. They usually get right in our face and sniff all over, trying to figure out where the noise came from.
All of my cats also seem very concerned at any loud noises we might make, whether it be laughing, cry, yelling, or my favorite, whistling. Like Ruttluver says, they will get up in our faces to sniff and see what is the matter.
In particular, my hellcat Claudia is very seldom what one my call 'sweet' or 'affectionate,' doesn't like being held, doesn't like to cuddle, never comes when called, very rarely even tolerates being petted. Doesn't like other cats or dogs, which is unfortunate as she lives with 2 dogs and 5 other cats. Hates cat toys. Will attack any cat she sees who degrades itself by stooping to playing with a cat toy. Cat nip only intensifies her urge to smack other cats. But we have discovered, by mocking her one day, that if you want her to be a sweet, cuddly lap cat, all you need do is make angry cat growls/yeowls. Instantly she is appeased, will run from the other room to check on you, jump in your lap and consent to attention, she even will give kisses. Apparently she isn't as big of a bully as she would lead us to believe.
