Update! I have been sick, so I had to do it a bit at a time, and I still want to add a loft, but I am (mostly) loving the new cage after the modifications I made! I put a linen closet wire shelf on the back, and then raised the roof of the other two grids by 1. I hope that makes sense! It's a backwards, vertical L lol. I'll see if I can attach some pics.
It's so roomy for the boys, they never ever fight like they used to. They still do their dominance dances, but it never escalates now, because they have room to run away. I bought casters that I had to drill into the legs of the table, but it was easy enough after I worked out how it's done.
Cleaning is actually easier than it was even in their smaller cage, because I'm not having to bend over as far which is a lifesaver because I have a bad back. It goes so much faster now, I can get to everything this way.
I will ill say though, had I known what design the finished cage would have been, I'd have opted to do a wood framed cage instead. It's fine as a c&c, but it would look better and I think function even better as a wooden framed one. When I have more time/money I do plan to work on making one.
Oh and Oreo had a haircut. The boys were getting a little wild with mounting each other, I just felt it was better for him to have short hair until they've settled down. He actually seems far happier without his hair! He popcorns really big, and he even wheeks now! He's like a different pig.
