After surgery the vet made sure to keep them right next to each other so they could see, smell, touch, etc and after we brought them home, we did the same. They gave the OK to let them together on Friday and it was like a prizefight. They were vicious. We separated them again (putting them in each other's hutch so they might smell each other or smell like each other) and tried again and the same. Today we tried again and one got a small cut on the tip of her ear so now I don't feel comfortable even trying again. We can't divide their kennel easily and I can't make them live in a hutch all summer so now on top of paying $400 for the surgery I have to buy new fencing and a hutch so I can make a second kennel. Since they'll have to be in separate areas (they will be right next to each other, sharing a fence, but still separated) they'll probably never rebond. I wish I never got the surgery done. I had no idea this would happen. They were so close-they are sisters and have been together since birth. They have always laid together, groomed each other, etc. Rarely fighting. I was told that they would start fighting and that they could get cancer if we didn't have them spayed so I did it. Now I regret it. And the worst part is how sad my kids are about it-especially my oldest, who is the one who mainly takes care of them. At first I said we might have to give one away but after thinking about it, I can't make my kids choose.
