I think he knows you helped him. Or at least he knows he was in trouble and that you were a resource to him. Last night I made a last effort at bonding my two male bunnies, and there was immediately a fight and one of the bunnies bit me sth terrible. I scooped up the other rabbit and held him so he didn’t come to any harm – and since then, he’s been really cuddly. He cuddled with me in bed, he came and lay close to my face this morning when we woke up, much more closely than he’s ever done before. It’s like he knew I saved him from getting hurt. (Of course he doesn’t realize it was my fault that he was ever in the risk of getting hurt).
In dogs it’s common that if you’ve once helped them when they’ve been ill or hurt, they know it and want to hang out with you, but I never knew it could be like this with bunnies.
I don’t know this of course, but chances are your bunny will project his sexual feelings towards you when he starts getting sexually mature, which he will be soon if he’s about 3 months old now. Because now he probably consider you bonded and sees you as extremely valuable. The running in circles around your feet is classic courting-behaviour.
