Double decker piggy hidey house?

[sazmatazz]

Hi all! I wondered if double decker igloos or similar exist, like piggy bunk beds? Dora likes to sit on the roof of whatever type of hidey house is available, whilst Poppy is on the ground floor snuggled. I'd like them both to have a hiding place, one on top of the other!
Any ideas?

We have a similar thing, but I wondered if there is one with a roof for the piggy on the top bunk? Esp for warmth in winter.
