PLEASE don't panic they DO NOT live together!The hutch is the rabbits ,every morning open the hutch for the guinea pigs, feed them first,then open the rabbits hutch to feed them and there are the guinea pigs walking up the ramp to the rabbits dish.I've even locked the guinea pigs in their hutch for awhile but they still go and help themselves to the rabbits food.(science selective)I was really worried at first when i got the guinea pigs,but the rabbits are really good with the guinea pigs,have not seen any nasty behaviour.Both Domino & Muffin have been neutered and spayed so they are very mild.The hutches are in a 'pen' that is about 12ft by 18ft.Lots of space for all.Most of the time they have the garden too,which is about 25ft by 30ft.Also escape proof!If anyone needs any more information or even photos to see how they are kept,I'm willing to do so!Just ask,I will not be offended!
