Thank you. They met at the shelter when I took Groucho to see if we could find a new companion. They got along right away. Groucho is 4 and Buggs is 1, according to their respective shelters. When I brought Buggs home, Groucho immediately loved him and perked up. He had been moping since we lost Bugsy. So, they hopped around and played and groomed each other, occasionally stopping to hump each other, each trying to be dominant. Groucho is used to being very dominant, as Bugsy was very submissive. Oh, both male and neutered. It's funny. They are both in the cage now and Groucho is worrying over Buggs because I held him and took him to meet a neighbor. Groucho always worried over Bugsy when I'd hold him. Groucho doesn't like human affection. So, I guess it worries him when the other buns get it (Buggs is super affectionate). They are fine right now. Have been for hours. They just get into worrisome scuffles every so often. At this moment, Groucho is cleaning Buggs like crazy because I held him for so long. Their behavior is so confusing!
