Most neutered buns recover fine within 3-4 days. But, you cannot exclude the possibility of infection and refusal to eat, which can escalate to serious complications. Since Friday will be about 3 days, I think that as long as his eating and toilet habits have normalized, keep him home. It will be less stressful for him. If your friend is able to check on him often, that would be best. If she cannot check on him frequently though, it may be best to have him stay with her.

I would probably opt for not leaving him alone. As mentioned, most boys are fine but there are possible complications. Like one of my boys, who started picking at the area, causing bleeding and had to wear a cone. And appetite and poops should be closely monitored after any procedure.

If you leave him with someone, you need to have a very serious discussion that they cannot take the job lightly. They need to be attentive and keep you in the loop, as well as avoiding doing anything that may stress out your rabbit.

Give them an extensive overview of your rabbit’s schedule, expected behavior, and what signs of discomfort, agitation, etc. will be. My careguide for Wick includes defining how his flops look, what he does when he’s upset, his vet’s information, and warning signs for common ailments which may come up.

can you not re schedule the neuter for a time when you can be home for the recovery?
