Weasley

I have a new member in the family.
I had already had a bunny before, even though she was a belier and this one is a harlequin. The other bunny was my sister's, so I haven't had her since I was little and I don't really know how to make Weasley trust me and feel comfortable.
There are more animals at home, they are all always very respectful and know how to leave him his space, even though Xerxes, my cat, is always watching him and he is the one who was most attached to me, another bunny Khaleesi.
Any recommendations to make Weasley feel comfortable in the house and with me and the other members?
