Hi there! Well it could take up to four weeks for the spraying and other horomonal behavior to die down.

You’ll want to make sure he eats all the way up to his surgery and right afterwards (they cannot throw up so no need to fast them; also their digestion system relies on constant digestion so they must not be fasted).

Make sure you get some pain medication when you leave-some vets just don’t give it unless you ask-so ask! They generally give metacam.

He’ll probably be sleepy or dopey for the first couple of days and then back to his old self-and generally calming down over the next few weeks.

I find that usually the males recover pretty quickly from a neuter unlike the females who take awhile to recover from a spay.

There is no guarantee that this will stop his chewing or his spraying though.

Rebecca-

Is he staying overnight at the vet or sending him some same day?  It seems like most vets send home same day- but I have heard some owners mention that there bun spent the night- more so for spays than neuters, I believe.

Neutering is usually quicker and less invasive than a spay- a spay is much more of an abdominal surgery- and that is why the boys usually bounce back quicker than the girls do.

Expect that when you bring him home that the vet will want him kept quiet- and you can offer food to tempt him to eat again- usually they will eat their favorite greens first, hay and then pellets.  It can take a day or 2 to get them back into normal eating routine and normal amounts of what he usually eats.  It is important to keep him less active to give the incision a chance to heal, and to keep him in a temp controlled environment after you bring him home- as anesthetic can affect the bodys ability to regulate temperature- you don’t want him too hot or too cold- just what he is usually used to inside the house should be fine.

Usually the vet likes you to check the incision at least once to twice daily to make sure it is healing well and the bunny is not licking excessively and preventing it from healing (saliva/licking inhibits healing).

Make sure not to fast (remove food) before you take him in for surgery- this is normal to do with dogs and cats as they might vomit- but since bunnies do not vomit and have sensitive GI tracts it is important to keep food moving thru his system- so no fasting before surgery and get eating again as soon as possible after surgery.  I took some greens and a treat or 2 with my bun when she was spayed so it was offered to her when she woke up.  Mine would not eat immediately after waking up, she did not eat until I brought her home that afternoon- but others have reported their bun willing to eat at the vet after waking up. 

Don’t worry. Everything will be fine. I just had my rabbit spayed and now she’s doing great. Expect him to be really groggy when you bring him home. I worried about Lily at first. She was so out of it and it made me nervous, but once the drugs wore off, she started to do a lot better. She was quiet for a few days, though. The pain med really helped too. I recommend them. She also didn’t eat at first. The vet recommended just mixing a little bit of dry oatmeal with her food. they recommend 1/4 of a cup, but I thought that was a bit much so I added about a tablespoon. She loved it. I would also recommend keeping him in his cage for at least day. Other than that, you should be set. Oh, and don’t be afraid to call the vet if you have any questions. I kept them on speed dial. lol.
