Yes, they do not sound like your typical house cat. They have more of repeated chirps. When they get made they have an awesome, intimidating growl that will back anything off. They are very friendly but a bit possessive of the people they own. They do love water. My Savannahs are hard to keep out of the shower. Of note, they tend to be shy with strangers so they will run and hide when people come to my house. After a while, if my guests are quit and calm they will come out and be friendly.
