I had my rabbit neutered shortly after I rescued him because he was already almost a year old and I didn’t want to wait any longer on doing it. At that time, I didn’t know much about bunnies but here’s what I wish I knew:
The clinic that I had him neutered at stitched him up a little wonky and the sutures ripped open on one side almost as soon I got him home. I’m assuming this happened when he was hopping into his litter box to wee. I certainly wouldn’t use a very tall litter box to where bunny has to do much work to get in and out. After bringing him back to get his sutures fixed, I just laid litter down into the corner of his cage where he usually goes and he seemed to know what to do. It was a mess to clean but I didn’t want him in much pain.
They did not give me a syringe, instead they instructed me to hold him under warm water and sort of let the water run lightly to rinse him. I’m sure every situation will be different and your vet should know what to do. Don’t be afraid to ask like I was!
If your rabbit has a water bottle, I would immediately replace it with a ceramic watering bowl, or offer both to bunny. I did away with my bunns water bottle after neutering anyway, but if bunny has to do work to drink from a bottle he will be in pain
I used my hayrack for him but made sure it was exceedingly overflowing and lowered all the way to the bottom of the cage so he didn’t have to work much to get at it. Keep an eye out when you bring him home and see if bunny is comfortable with the hayrack, he might be okay.
I would suggest bringing an open top carrier to the vet with lots of blankets. You want bunny to be as comfortable as possible. I made a huge huge mistake of bringing a closed top carrier to the clinic with only one blanket and he was miserable on his way home ?
