Hi fellow bbers I have an issue and i’m really worried and I need some advice! My girl (6 mths) was spayed yesterday, and healthwise she’s fine. She has a brother (neutered, 8 mths), and they were bonded before her spay. I even took him to the vet with her so that she’d recover quicker (as recommended by my vet). When I went to pick them up, the vet said they were really good. So i took them home, and they were fine together, both in their cage and while they were running around. I separated them when I slept just in case. This morning, when I let them go together in their cage, they were still fine. However, just a few hours ago when I tried to let them out, my boy started chasing her and nipping her as well. She was terrified. I immediately put him back in the cage and left my girl out. But now when she passes by his cage, he goes crazy, running around like he wants to charge at her or something. So now I have no choice but to separate them. What’s wrong? Will he be aggressive to her forever???!! What can I do???
