Hi all! Thank you all for all your great advice on this forum! Here’s the dish….
Buster (full breed Polish) and Hermione (mix breed English Angora and rescue rabbit) are both 7 years old this year and been together since they were both less than 1 year old. They initially bonded before he was neutered (very smoothly, may I add, he sprayed her and that was that = love). There have been a few spits and spats over the years (he worked in show-biz as a magic bunny, now retired), but generally they have been in love. She has been in ICU 3 times total for GI stasis and pulled through each time, no problems with the love between them when she got back from vet. For the first time, he went to the vet (overgrown molars), went to OR, now home. He and her have both been confined to their individual cages while he’s recovering and beginning to eat again without pain. He’s been looking at her through the cage bars longingly. She could care less. Me and hubby are switching potty-boxes, rubbing scents…it is obvious he misses her a great deal, she remains in her own world. Since he seems to have recovered, we decided to let them into their playpen, on their “usual” schedule they have had for the past 7 years….holy cow talk about fur flying! He tried to kiss her and she ripped his fur out and nipped at this face, flank, and any other place that got near her. We pressed her face/chin to the ground in submissive pose with a loud NO! and got him away from her unharmed. We waited a day, placed the bottom of one of our carrier cages in the tub and simulated a car ride by gently shaking it side-to-side. For the most part, Buster sought solce with Hermione, she could care less. She sniffed him and few times, groomed herself, kissed his ear once, shoved all 8lbs of herself underneath his little 3lbs body (per their old usual). He didn’t groom her though the way he used to. Just hopped (slid) away, groomed himself and squished himself into a corner. Hubby and I carried the box (now lidded) into the living room to just watch them. Overall, he sulked in the corner, she alternatingly ignored him and nipped his face (she nipped or looked aggressive and we shook the box and she’d stop and wink). This all lasted maybe 1hr total.
Now what? Just keep at it? Will we somehow “know” when they are in love again?
You all probably know our fear is they won’t re-bond the way they were. It’s almost like Hermione has gone senile! 
Thanks!
