I have never heard LuckyGirl hiss. Ever. Even, if you annoy her and she doesn't wanna be held again, even when I had a dog in the house (clearly she was not happy), even if you put food down and then take it away, or put your hand over the food. Nothing. She won't hiss or growl at all ever. Hubby says it's cause she's just so greatful to have a home and food and love that she just never complains about anything. But is this normal? Does anyone else have a non-hissing cat? Just curious.....
