How to start rebuilding? - 2

[Hoju]

They are brother and sister and have never spent a day apart in their lives. When we got them W only wanted 1 and I said lets get 2 so they would have company when we weren't there. We were given these 2 because of how close they were as kittens when the family had originally intended to keep the male. They are as bonded as cats can get, it kills me to break them up but this isn't my choice. Why should I be the one who keeps suffering? Any guilt from breaking them up should fall on W not me.
