When they start chasing, how severe is it? Do you have to intervene or does it stop on it’s own?
First thing, make sure no one has actually been injured. If anyone has any injuries, I hate to say it, but you need to separate them and go back to bonding. But it sounds like it’s prob just some chasing and lunging?
When Tillie gets aggressive, is it in response to something Max does?
Have there been any new people or smells in the house? New pets? New roommates?
My Bertha was getting cranky around breakfast towards Moose when their bond was new. She would chase him out of the litter box, and just act like a brat.
The things that helped them were:
-giving them 2 litter boxes (previously they had one huge one. The two litter boxes are side by side, and the same amount of space, but just having them be two separate boxes helped a lot.
– doing “couples therapy” – banana on both heads to get them both to groom more. Seems kinda like cheating, but it worked, and the effects lasted long after.
– doing a bit of stressing – car ride together in the carrier
I also started giving them their pellets in separate food bowls (even though they will eat out of the same one). Also make sure they have tons of fresh hay overnight, so they eat lots and aren’t so ravenous in the morning.
The other thing is to make sure both bunnies are healthy. If one isn’t feeling right, either they can lash out at their partner, or the partner can get grumpy with them. In my case, Moose also had a rotten tooth, so I think he wasn’t grooming Bertha enough for her liking….
In my situation, I changed a lot of things at once, so I’m not sure what was the most important, but I think maybe they were all factors, because I did see improvement with each change.
In terms of toys: Mine like shredding phone books, cardboard cat scratchers, the “barrel roller” toy, the “knot nibbler” toy, they love their willow tunnel, sea grass and timothy mats, and concrete building form tubes (from Home Depot) for tunneling. Moose also has a tiny cowbell which he loves throwing around. I recently got stacking cups (recommended by someone here) for babies… the buns will knock them over whenever I stack them up! My Bunston also used to pass a cat “batta ball” back and forth with me
