Hi there! They are freaking adorable!! And i love the decor!

So you can put out healthy treats around your place so he will want to go to those places to get the treats! And then add more rugs if you can(can be cheap, just so he can feel more comfortable roaming), but you should also have some safe hidy houses so they can go there when they get scared because they are prey animals, they need to have some place to hide to feel safe.

I also suggest to not keep anything on the ground that they can eat, Put the hay in a plastic bin(but make sure they can’t get in the bin so they don’t get trapped) as they can eat the plastic and get it stuck in their GI and get GI stasis. Also, make sure that there is nothing breakable or chewable within jumping distance of them so they don’t get hurt.
You should also look at houserabbitsociety to see how to bunny proof your place, your house is their house now and you just live in it haha, thats how we all feel.

What gorgeous rabbits

Do you have a few hidey boxes around? Perhaps if you have some boxes and tunnels around, he’ll feel safer exploring because he’ll know he has somewhere safe to retreat too. Using treats might help too.

How long have you had them? Are they free roam? If so, you could try limiting their space a little and gradually increasing once he’s comfortable so the entire space isn’t as overwhelming

They are adorable! I know you said you don’t think it’s the flooring, but from those photos, they’re both always on the rug or carpetted areas, so I think extra rugs might help!

Boxes are great too – I ask the local shop for cardboard boxes then cut a few doors in them. My bunnies currently have 5 dotted around the room and they love them.

My bunny has taken her sweet time getting used to different spaces based on totally arbitrary boundaries that she’s come up with for herself. She sticks almost solely to our entryway/living room. It took her a month before she ever attempted to jump on the couches (and now I wish she would stay off them…) and then just this past couple weeks, after four months, she ventured past her imaginary boundary of the front area rug and followed the cats under the dining room table. Until then she would just stop at the edge of the rug and never go further. She’s still never ventured down the hall or into the kitchen. I do think rugs make a difference (all of our bun’s imaginary borders are the edge of area rugs and we have hardwood floors) but I think just giving them time will help too. Our bun’s self designated living space is large with space to run and little den hidey holes so I don’t worry about her feeling trapped by the fact that she doesn’t want to cross the rug.

Karel might just need more time and encouragement from you to explore. My bun can be bit of a coward too when it comes to new spaces. I’ve noticed that he’s more daring if I’m nearby or near enough where he can see me. Like I’m a sign that the area is safe. So try sitting nearby or bribing him with treats. He’ll eventually make it over there. Then you’re problem will be trying to keep him out of certain areas lol!

Nothing else to add but those are ridiculously adorable little puffballs! Not helpful, I know, but had to say it.

SO FLUFFEH.

Bunnies have such different personalities and I think you just need to give him some time
