we bought one from this seller about 18 months ago and were very impressed with the quality. They are quite heavy as well – which is reassuring
The longer entrance hall on some is quite good at keeping draughts out of the house apart from anything else – hogs don’t like draughts! but it is also good at putting cats off because cats don’t generally like the tunnel that they cant see the end of. I’m always conscious of the badger and fox issue as well, so anything that deters them from sticking their noses or paws into to explore can only be of benefit to the hog.
Having said that – this type of house has been no more or less popular with our resident hog population than ones that don’t have a slate roof or tunnel. we have tried the hogiloo, too, which is the recycled spiral type – which some winters has been ignored completely and at other times fiercely coveted by several prospective inhabitants (which is quite funny to catch on the camera’s – with hogs even hiding in wait for one to exit, then dashing in to claim occupancy – only to be turfed out again the next evening).
