Hi,I'm in Ireland so it's quite difficult and expensive to get grids and coroplast. The last time I was in pets at home I remember seeing quite a large cage(I think it was around 5 x 2,but I'm not 100% certain) I have two female guinea pigs,that get along very well. Would it be a good sized cage for two? I also have a rabbit,two VERY noisy cockatiels and a dog in my room at night time only but he's great with the Guinea pigs. Would the noisy cockatiels stress the guinea pigs out? Any cage suggestions?
