I bought the coconut for my Dzungarian Zwerghamsterin. A golden hamsters would there not fit, small hamster, it is perfect. I pulled the string through a hole in the cage cover and knotted (I have a wooden plate as a lid on my tank and no conventional cage), the attachment was so very easy. For normal cages of carabiner for attachment is ideal. I like to hide a bit of food in the coconut so that the animal has the incentive, since climb and that makes them happy and easy. A nice change for Hamsterton =)
