Such a shame when kitties just can't gel. I'm so sorry.

Your statement that most people that love cats probably wouldn't want just one is just not correct, however; there are many (including my husband and myself) who feel they are best as a one cat household, so your kitty will, I'm sure, be able to find the right place. I hope it's with your family so you at least have visitation privileges.

Please keep us posted and best of luck.
