Our neutered boar has doubled his coat overnight 
Grazing days are getting fewer and shorter (they had an hour yesterday late afternoon)
We insulated their Pighouse with cardboard and polystyrene (where they cannot get the rodenty little teeth on it)
GP6 can make his lovely thick bedding last 2 days whereas his cagemates (GP7 and GP8) are very messy girls who need daily bed changing. No sitting in wet bedding for my spoiled piggies but I do wish they'd use a litter tray like other small furries .
We have Snugglepads to pop in the microwave (I don't use the fleece covers they stink after 1 day. Mine are wrapped in newspaper and tucked right under their newspaper bedding to keep them safe)
Card shredding equine bedding on the floor. Easy to spot clean, no dust, soft and insulating underpaw.
They come indoors to their wintercages once it gets too chilly outside. We give them the small bedroom so they don't overheat (though they're noisy little ratbags 
)
GP2 used to need fattened up , don't think we'll have that problem with these 3 !
Its always a shame when the seasons change , they do love being in the garden especially late evenings................but we can always cut grass until the lawn is baldy.
