Sure it's OK! its the greatest feeling when all my babies jump in bed with me surrounded with all this fur
from day one when I brought each one home, they slept in my bed right off, no crying or wimpering! I dont believe in putting my animals in a crate, it's ok if you live in apt I guess but I only use the crate for traveling for their safety! but they would jump down to go potty! good luck and enjoy them sharing your bed
