sorry to hear about you having to take cinnamon back, but sometimes it just doesn't work out. I definately would go for an older, more mature cat, but watch out! they can get wild and crazy also. i got pitter and patter five years ago when they were about a year and half and in the the first six months they broke a ceramic coffee pot from israel, knocked the christmas tree over about four or five times and broke ornaments on it. and in the last two weeks they broke an antique plate. I chalk all this up to them being cats. i've learned if you don't want it broken put it away or secure it tightly. good luck
