My boy bun was actually full of energy when he came home from his neuter. He was banging around in his carrier the whole way home and was VERY flustered that the 2nd level had been taken out of his bunny home. LOL. And that he was in a confined space. And he actually gobbled up a TON of food when he got home…. but then as the meds started to wear off you could tell he became a little less active and would sit in the corner with his rear off the ground a bit but when we gave him his next dose of pain meds he was fine and back to being all giddy and angry that he couldn’t run around like usual.
I would be prepared to have to check his incision though — that was probably the hardest part of the whole process for me — that and getting him to take his meds (after the 3rd day he was having none of it). We basically managed to check his incision by getting him to stand with his front paws up on something (we put up one of our tiny fences around his cage so when he came out and would want to get out he’d of course walk up and want to jump over the wall so when he put his paws up I’d put the flash light down next to him and check it quick. Another way could be by holding up a piece of his favorite treat so he lifts up to reach it and sneaking a quick peek then too!
My buns go back and forth on what treats they like and prefer but the one thing I can never seem to go wrong with is craisins. They will literally all tackle me (even our skittish bun) to get to the bag of craisins. It only took a little prodding to get one of them to try it and it was all over from there…
Also, any of his dishes/food/hay that he may have to reach up to get to I’d suggest putting them really low to the ground so he doesn’t have to do any stretching to reach them… if he has any toys that hang from the ceiling I’d take them down also so he’s not tempted to be overly active. My overactive bun went nuts being so confined and was really angry but once we gave him lots of attention and play time afterwards he was really fine.
