Hello all,

I have two 8 month old holland lop buns, both female. They were both spayed on the same day at the end of July. A few weeks before the spay, Rae started humping Stella. She would hump her from behind and from the front, which I know is bad. Stella was not a fan and would then chase Rae around and that was really it. They were spayed and we didn’t have problems until today. Today I found chunks of hair in their pen. I didn’t know what happened. I watched them for a while and nothing happened. Tonight I let them out for zooms and Rae started humping Stella from the front again. Stella then got mad and chased her. I don’t know why this is happening. Nothing has changed. They go to the vet together, zoom and explore together, they have the same toys, food, water and setup as always. They have always been cuddly with each other and have basically been glued together. I don’t know what is making Rae feel the need to hump all of the sudden. I have separated them for the night because I am worried one will hurt the other. I put a pen panel in-between them so they can still see, here and lay next to each other. Am I doing the right thing? I don’t want to un-bond them by keeping them apart. Do I just need to let them sort it out? Keep them apart? For how long? There has been no bleeding or visible injury, just chasing, humping and chunks of hair.
