I’ve had my rabbit, Miso, for about two years now, and he’s always been the chillest little guy. Lately, though, he’s been thumping his back legs almost non-stop, especially in the evenings. I haven’t changed his diet or routine, and I haven’t noticed any new noises or disruptions in the apartment. I tried giving him extra cuddle time and hiding spots, but nothing seems to calm him down. I’m worried because the thumping feels like a clear sign he’s stressed or scared, but I can’t figure out what’s triggering it. Could it be something subtle I’m missing, like a smell or vibration? Has anyone else dealt with a sudden shift in their pet rabbit’s behavior like this? How did you figure out the cause and help your bunny feel safe again?

That nonstop thumping sounds really stressful for both you and Miso. Sometimes rabbits pick up on things we don’t notice - like a neighbor’s new pet, a faint noise outside, or even subtle changes in air pressure or smells. One time, my friend's bunny started thumping like that because of a new cleaning spray nearby that was invisible to us but overwhelming to him.

Since you’ve ruled out obvious changes, maybe try temporarily moving Miso’s space to a different room or rearranging his environment a bit to see if that shifts his behavior. Also, some rabbits get more anxious as it gets darker or quieter in the evening. A soft night light or gentle background noise might help him feel less on edge.

It’s tough when our pets can’t tell us what’s wrong. Keep observing little details, and maybe try to catch if the thumping coincides with anything specific - sometimes the cause is something tiny but meaningful to them.

That persistent evening thumping really sounds frustrating, especially since Miso’s routine hasn’t changed. Sometimes rabbits pick up on subtle things we don’t notice - like a neighbor’s new pet, a faint smell from outside, or even a change in light or shadows at dusk. I had a bunny who started thumping suddenly, and it turned out to be a stray cat hanging around outside the window, which stressed her out even though I didn’t hear or see it at first.

Maybe try observing Miso closely during those thumping episodes - see if something in the environment shifts right before he starts. Also, some rabbits respond well to gentle background noise like soft classical music or white noise to mask subtle sounds that might be bothering them. It’s tough when they can’t tell us what’s wrong, but sometimes these little environmental tweaks help calm them down.

That nonstop thumping in the evenings sounds really tough, especially when Miso’s usually so chill. Sometimes rabbits pick up on things we don’t notice - like a neighbor’s late-night noise, a subtle scent from outside, or even changes in light or temperature as the day winds down. Have you tried spending some time just observing him during those thumping episodes to see if anything else changes around him? Sometimes the tiniest detail can be the clue.

I had a bunny who suddenly started thumping more, and it turned out to be a small critter (like a mouse) in the walls that only came out at night. Once we figured that out, adding a little white noise helped mask the sounds and calmed her down. Maybe something similar could be happening with Miso? It’s frustrating when you can’t pinpoint the cause, but your extra cuddles and hiding spots are great - it shows he’s got a safe place with you.

It’s really puzzling when a usually calm bunny suddenly starts thumping like that, especially without any obvious changes around him. Sometimes rabbits pick up on things humans don’t notice - like subtle shifts in lighting, a new scent from a neighbor’s cooking, or even vibrations from nearby construction that might not be obvious to you. Since Miso’s thumping spikes in the evenings, maybe try observing if anything specific happens around that time, like outside noises or even your own routine changes that could be unsettling him. One thing I found helpful with my rabbit when she got jumpy was rotating her toys and hiding spots to keep her environment feeling fresh and secure. Also, sometimes a gentle routine of quiet, slow petting can help, but only if the bunny wants it - some get more stressed if they feel cornered. If it keeps up, a vet check might be worth it just to rule out any discomfort or health issues that aren’t obvious. Hang in there - bunnies can be sensitive little

That nonstop thumping sounds really tough for both you and Miso. Sometimes rabbits pick up on subtle things we don’t notice - like a faint noise from outside, or even a new scent on your clothes or furniture. Have you tried changing up his environment a bit more, like moving his cage or play area to a different room for a day or two? It might help pinpoint if something in the space is bothering him.

Also, since it’s mostly in the evenings, maybe there’s something happening around that time - like neighbors coming home, or a change in lighting - that’s unsettling him. I had a cat who suddenly got jumpy at night, and it turned out to be a new streetlight outside shining through the window. Maybe a similar small change is throwing Miso off?

It’s great you’re giving him extra cuddle time and hiding spots; sometimes just being there calmly can help even if you can’t find the exact cause right away

That persistent evening thumping really sounds frustrating, especially since Miso’s usually so chill. Sometimes rabbits pick up on subtle things we don’t notice - like a faint noise from neighbors, or even changes in air pressure or lighting as the day winds down. Have you tried spending some quiet time with him during those thumping episodes to see if any particular action or object seems to trigger it?

Also, since you mentioned no changes in diet or routine, it might be worth double-checking for any small pests or drafts in his space that could be bothering him. I’ve seen a friend’s bunny start thumping because a tiny spider was hiding nearby, totally invisible to us but clearly not to the rabbit’s sensitive senses.

Hope you find a clue soon - sometimes it’s the tiniest detail that helps them feel safe again. Keep us posted!
