I have one male and two females and by far my female Jazz is the sweetest. She's unusually sweet according to my husband.

Ripley has never been what you would call sweet but he has his teddy bear moments. Unfortunately he has some anger issues. One vet told me he has Feline Rage and it is mostly directed at me. It has calmed greatly with age but he still has his "fits". It's very scary to have a 20 pound cat stalk and attack you. I have the battle scars to prove it on my legs and arms.

His behavior is one reason it took me over 10 years to get a second cat. Jazz's sweetness is what made me want a third cat.
