I just upgraded my hamster's enclosure- a guinea pig wooden cage that measures 150 cm by 60 cm by 45 cm.. Which I read is apparently the minimum cage size for 2 guinea pigs. Having seen my Syrian hamster in this new cage, I don't understand how this size is suitable for guinea pigs? I never had guinea pigs (though I have considered them before and read up a lot about them before); but my hamster utilizes every bit of space in the cage. And a guinea pig is 4 X the size of a hamster and is active for 20 hours a day. Plus there are two of them. Are guinea pigs less active than hamsters?
I am not saying that its wrong to put guinea pigs in a cage of that size but the minimum standards for the various small animals don't make sense to me:
Hamster: 100 by 50 cm for Syrians; 80 cm by 50 cm for dwarf hamsters
Guinea Pigs: 120 cm by 70 cm or 150 cm by 60 cm (depending on what you read)
Rabbits: 3 m by 2m !
Guinea pigs are so much larger than hamsters so why is the minimum requirement for them only 20% larger? Plus they are a social species. I never thought much of the requirements, but now i have a cage that is that size; I actually realize its not actually that big.
