And yes, the area will encompass the old Prezwalski horse stable, so the porcupines are only temporary residents.
That's a shame, they were making a nice addition whilst on show (I seem to remember them in Secret World of the Okapi many moons ago when it was still the Camel house.
It would be nice for the zoo to find a permenant on-show area for them (Welsh Mountain mix theirs with their meerkats, so maybe this could work well at Chester?)
