I am fully aware of the cage requirement for my two guinea pigs and they have a 120 indoor cage aswell as a 4ft hutch and a 5ft run. Now the weather is getting better they are spending more and more time outdoors. The trouble is I have no where to store the 120 cage. I was wondering if I could downsize to a 100 as they don't seem to do much running and I've hardly ever seen them pop corning around the indoor cage and now I have the run in winter I intend to keep them in this in the kitchen, and the cage just for sleeping.
