Jeff and I have also experienced this with our ferrets. We got Hershey as a kit and tried to introduce her to our existing pair, Ben and Jerri. Ben was okay with her, Jerri was not. So Hershey stayed in her own cage and had her own playtime. Then, about a year later, we got Casper as a kit. We introduced the two of them and it was love at first sight. We had other ferrets over the years, and Casper was the only other ferret that Hershey would tolerate. She slept cuddled up together - usually hugging - in a hammock and played together wonderfully. We could let Casper out with the whole group, but not Hershey. After Casper left us for the Bridge, we gave Hershey some time and tried again with no luck. She was in her own cage and had her own playtime until it was her time to go find Casper at the Bridge. I always envision them side by side exploring the wonders at the Bridge and sleeping with their paws around each other in a big hammock.
