That is a long time. You need to somehow get the word out to someone who only wants one cat, and that is the hardest thing for a rescue group to do! We go to Petsmart, Petco, and vet's offices...where we find people who already have cats, and often other pets as well.
Try to spread the word among friends. Have the other members of your group put out the word about this wonderful cat, who wants to be an only cat. Can CJ be posted on a website, and maybe on Petfinder. Can he be highlighted as a pet of the week?
Best of luck to you, I hope CJ finds a forever home eventually! I never had one that long, but I have only had a few since April 2004.
