Ferocious Lions??

Carrie and I are cat sitting for another teacher while he is in the States for Christmas break.  We are excited to do this but were a bit concerned about what we signed up for when we received the e-mail of instructions.  It was long and it told us many helpful things but I was wondering if we were cat sitting for cats or if were sitting for ferocious lions.  When we went today the picture below is what we found.  We were able to hold these really scared cats and they even ate out of our hands.  They are cute and we will enjoy feeding and petting them but I hope they start to calm down a bit so we can hold them for longer periods of time without them having little kitty heartattacks!
