Hi I have 4 piggies one of which is a skinny pig and I always drive myself crazy when the weather starts to turn. I keep all my pigs inthe house and all have their own wooden beds they can go into ,with fleecy blankets and extra hay but I still worry about my skinny, Godfrey he's 10 months old now and has a special heat pad I warm up in the microwave for him every 6 to 8 hours , including waking during the night to reheat it . Does any one know of any other good heat pads that stay warm for longer or any special bedding that will keep in the heat? Any suggestions would be much appreciated.
