Hi everyone!My older rat Tofu had surgery to remove an abscess two weeks ago. Because of the open wound our vet suggested that Tofu and Button live separately until it has healed. We have a large aquarium that we tried to move Tofu into but he wouldn't stop trying to escape so Button, who had already lived in the aquarium after his eye removal, was put in the aquarium instead. The aquarium was pushed against the cage so that Tofu and Button could still hear, see, and smell each other. Now Tofu is already healed and during the two weeks of healing they did visit with each other on the couch. There was a lot of pushing, boxing, fur ruffling, cleaning aggressively, squeaking, and an occasional hiss. We tried putting them into the cage together but even there they fought. It's a pretty equal amount of aggression from both parties. Does anyone know what could be wrong and how to go about getting them to be friends again? Before Tofu's surgery they loved each other and cuddled all the time! Please help!!Thank you!
