Hi,I have two female guinea pigs that are well bonded,they are getting a new cage,it's a pet store cage(120cm x 60cm which is the rspca minimum guidelines. I still felt this was too small so I ordered two,and I'm joining them together so it in total the cage will be 8ft x 2ft.Opinions please? It worked out much cheaper than a c&c cage,the postage for grids makes it very expensive.
