"Nice that you have them next to eachother cause the cute li'l buggers can die from lonelyness.
For that reason it's actually illegal in Sweden to have a cavy solitary in a cage."
All I can say Is WOW. Anyone else hear of this before?
Great law, but it also states that guinea pigs should have a salt lick!
If you google "jordbruksverket marsvin" - the government agency that made the law and the Swedish name for guinea pig (which you might have learned from IKEA...) the pamphlet is among the top hits!
I can't imagine you could force to have two pigs in a cage. What if they don't get along with others?
The law is called DFS 2005:8 saknr L80, and can be found on Jordbruksverkets website.
It also states that minimum cage size is 3.2 square feet, wire bottom cages are not allowed and guinea pigs must have somewhere to hide. They must have access to hay and get vitamin C on a daily basis.
Good advice, except for the cage size of course!
No more than ten animals should be kept together and if grown animals are introduced the environment should be changed so that it is new to them both.
By the way, this law applies to all persons that keeps guinea pigs, for example private persons, breeders and pet shops.
