accessible for kitties.
for storage remove spiky collars and reposition so they lay flat on box.
could you wrap the box before you put the books and stuff in it and just leave one side folded as a flap and then tape it?
i have actually done that a few times but i always see the seams. the best i did was i took the box and attached the gift wrap with spray adhesive and then made the box around the tree as usual. it can be done!
