I just finished my cage today, so i havn't gotten my piggies yet. I still have plenty of time.. i'm in no rush. I just wanted to know what you all thought of it. Any suggestions or comments are highly appreciated. I had to use linoleum because i really didn't know how i could make coroplast fit into this cage. Its not exactly a rectangle. It has a few obtuse angles. I had to do it this way because the space that i wanted it to be (right next to my computer which i am on A LOT!) only had room for either a 3x2 cage or what you see here. I think it will work fine though. The lower level is 4x4, but its kind of a triangle with 3 90 degree angles and 2 170? degree angles. The upper level is 2x2. One of my questions is that the upper level is going to be filled with Timothy Hay.. will that be enough for my little guys, or should i also add some to the lower level as well? I'll try to put a photo on here, but i'm exactly sure how to do it, so i'll try. Thanks in advance!
