What do you think is the difference between minimum space and preferred space?
I think most of us have seen/heard that guinea pigs have minimum and preferred space requirements. But personally, I never heard anyone explain the difference between the two. If it would be bad for guinea pigs, it wouldn't be called minimum space. And we all know that the larger the space the better and the best thing to do is to buy the largest cage that can fit into your room. I think it's because some guinea pigs are more active than others and the prefered space is when it's 100% that it's enough for them.
I also think that below the preferred, it's good to give them floortime more often, especially when the cage is like exactly as big as the minimum, even if the pigs don't seem stressed about it, a few hours every day or even every other day is always good.
But this is just my idea and I'm curious about your opinions or if there's an official explanation!
