Oh I know, that's why I'm not moving the divider until she's spayed and recovers from it. I have let them meet without the divider twice. First time was a lot of chasing, no humping but I think he did attempt but she ran and second time there was barley any chasing. Also, occasionally I'll see her groom him through the bars but he doesn't groom back even when she lowers her head. Is that normal? And don't worry, he is neutered
