my roommates and i have a cat about 7 months old. we were told it was a girl, but one of my roommates friends think otherwise. HELP! i don't know how to tell! i've always been a dog owner, and obviously its easier to tell the difference, but with cats its much more difficult. i tried looking on the internet, and the answers i received were vauge (sp?). is there any way i can tell the sex that is obvious? thanks for your help!
