Is it possible to make an outdoor rabbit an indoor rabbit ?

My buns love moving indoors, but they do still have access to the garden when they want, they like being in at night.

Yes, you can, we bring some of ours in when they are poorly or very, very old so as we can monitor them better

Mine prefer indoors BUT if they are outside they don't want to come back in, if they are inside they don't want to go out!!!!!

We have them indoors over the winter, then outside in the summer, but I do bring them in at night in case of foxes etc.

Absolutely, if it's what they want and you aren't too houseproud, then great
