Strange behaviour after neutering

Hi again,

My 5 month old buck got neutered on Monday and he is now acting really strange? He has circled my feet several times in the few days (he has done this once in 3 months previously), He also litter trained however, his litter habits have slipped, he will purposely leave droppings around the tray, he did do this prior to the neutering but not as much.

Is this supposed to happen immediately after a neutering? When will this calm down?

Yes some rabbits lose their litter habits after they have been neutered but usually return to normal a few weeks later. Food is usually why rabbits circle your feet, otherwise I have no other explanation. Maybe he thinks you have got what he has lost and would like it (them)back?
