Mimzy & Obi-bun have been bonded for a year now, almost exactly, they’re still sweet to each other (mostly Obi to Mimzy) Obi will groom her all the time, they cuddle, share food/water bowls (even though there’s 2)
But Mimzy every once in a while gets grumpy & goes after Obi for no reason I guess other than she feels like it or she’s frustrated & takes it out on her husbun! They don’t fight, she just chases him, lunges, or growls at him, sometimes she still mounts him?? & he just runs away waiting to love on her after she’s done throwing a fit. It’s usually when she’s hungry, but once the food is down she’s totally fine sharing with him. So lately I’ve tried holding one of them before I put the food down, & then let them both eat after it’s down. I just can’t figure out why she’s doing this if they’re otherwise so good together?
Is she just a grumpy bun who needs to get frustrations out? I try to block her from chasing him every time (when I can) & thump at her when she does it but she just won’t stop & I can tell Obi doesn’t like it. Spraying water doesn’t seem to phase her much either. I’m at a loss!
I thought at first it was her still trying to make sure he knows she’s boss & that she would stop eventually but it’s been going on a while. Should I try bonding sessions again even though they’re fine living together already? They have plenty of toys that I switch out, always have hay & water, nothing has really changed. I just don’t get it 
She’s also still chasing & lunging at the cat, will she ever stop once she’s made her point?
Maybe I just have one adorable grumpy bunny
