Even if they have the igloo hideaway houses will they still need the snugglesafes
Yes, snugglesafes are essential for outdoor piggies.
Piggies need a source of heat or warmth, and the only way to provide that for outdoor piggies is snugglesafe heatpads. Hidey houses themselves do not produce any warmth.
(The only alternative is to use electric heaters to heat the whole garage all winter - this would most likely not be effective or energy efficient unless the garage is properly insulated and therefore will likely cost a lot of money).
You heat the snugglesafes up in a microwave and pop them in the hutch under piles of hay and hidey houses. They give the piggies somewhere warm to go. The hidey houses themselves then keeping the warmth within them. The company claims they stay warm for 10 hours but I find they are only really warm for about 8 hours.
I have four snugglesafes between my two piggies.
I find it best to use wooden hidey houses for outdoor piggies, not plastic. Plastic houses may get condensation inside them (particularly once snugglesafes are put underneath them) and mean piggies are exposed to damp
The way I keep my piggies warm enough by insulating their shed and their hutch. Being in the shed makes a huge difference and means they are generally 5-10 degrees warmer than the outside temperature.
Their hutch has silver foil insulation on it. It then has a thermal hutch cover. The next layer is two blankets. The next layer is a waterproof hutch cover (being in the shed of course means they aren’t exposed to rain but the hutch cover provides another layer of insulation and the plastic front means warmth can’t escape). I then pull an old duvet down over all of it during mid winter. All these blankets etc go on the sides and roof of the hutch.
All hutch covers are pulled down at night and removed during the day so the hutch can thoroughly ventilate. I may leave just plastic front of the hutch cover down during particularly cold days though - so coover air doesn’t transfer into the hutch but so they can still get daylight and see out .
Inside the hutch, it is completely filled with lots of deep meadow hay. The hidey houses also have hay inside them. i then put the snugglesafes under the hidey houses and by their timothy hay piles so they can eat and be on a heatpad. I have four snugglesafes between my two piggies.
The snugglesafes are used during the night primarily but also during the day when needed.
Any wet hay is thrown away and replaced every day. So having outdoor piggies in winter, you will get through a lot of hay!
I spent a lot of time each day heating up the pads (just over 6 minutes per pad, twice a day means I spend an hour a day just heating heatpads!), removing and replacing hay, checking the thermometer etc!
