I'll bet the twins aren't too hard to tell apart, even easier later, especially if they are differen't genders. I have had siblings before and can tell by the voices, even if I am not looking.
Hey you guys. Well, Jackson's head is a hair smaller than Ozzy's and Isabell has more white furr. I was thinking I'd use a marks alot to mark one of the boy's ears so I can start using their names. I think as they get older there will be some differences. If not, I suppose different colored collars would work until their voices and behaviors give them away. Oh boy, kittens!! I'll tell them about their new fans
