I’m not sure this helps, but lately with bouts of insomnia I have gotten up in the wee hours in the dark. Spike will hear me or see my dark silhouette and get scared like that. He’s 6 and should know it’s only me, but….

So I have started VERY softly saying “Spike it’s only me don’t be scared it’s just me.” And from a distance until I see he’s fully awake if necessary and looks calm. Bunnies hear 10xBetter than humans so yours might be startled by your noise before you know it. You can try reassuring them in a low familiar voice before they feel you sneaking up on them. Then nose rubs can be your next move.

I doubt you undid any of your trust!

Bunnies can spook sometimes. It can be very hard and scary to watch, and sometimes hard to know what spooked them. Myra is somewhat prone to this, and one of my bridge bunnies Moose was also very easily spooked. I usually stop whatever I’m doing, sit down, and speak calmly to her. I don’t try to approach her to comfort her, because a scared bunny reverts to their instincts that everyone who isn’t a bunny could be a predator. Usually if I stay relaxed and kind of just go about my normal business she calms down pretty quickly. If it’s something outside that is scary, remaining calm will appeal to the bunnies social instincts that if the herd is calm, then things are probably OK.

I completely agree with Pam and Dana. Rabbits spook easily, they’re hard-wired to do so. Even my bun who is of a very easy-going disposition, gets spooked sometimes. I acknowledge, but don’t approach physically. I talk to him softly, that generally does the trick.

You have not undone the trust they have in you. Once they have calmed down, you can give a few pellets or a small treat, if you wait several minutes after the thumping has subsided, they wont make the connection thumping = food.
