Hello! I was a wreck the first time I brought a boy in for a spay as well (so much so that I even teared up when the vet took him into the back…) but everything went just fine. When I got back in the afternoon they brought him out and he just looked at me like “hey mom, where have YOU been?.” I know its tough to keep them in a cage for a couple days, but its a very good idea because their little “area” will be very swollen on both sides, and there are also incisions on both sides, and the first couple days they will probably be pretty visible and sore, so you reallllly don’t want y our bunny leaping or jumping and hitting or opening those incisions (because…OUCH!! and because he’d have to go BACK to the vet to get them tended too). Also, because he’s in the cage you’ll be able to keep tabs on him and see if he’s eating, and give him some treats, and be able to get ahold of him and turn him over to check how he’s healing. Also, think about getting him a litterbox that low on one side (I use a carrier bottom) for the first couple days so he doesn’t have to leap over the side and risk hitting the surgery area.
Good luck to Floppy – he will feel much better when he’s healed
