Compared to c&c cages they are just a bit easier because you don't have to run about finding parts, etc. I love how easy it is to separate the sections with the dividers and then how they have openings in them that can open or you can put a ramp in between.
While I wish I had found these sooner, I don't need them now. We have 1 6x2 grid cage, a 2x2 grid cage, and 2 2x3 grid cages, plus another 7 or 8 cages for piggies. But they look awesome, and the cost isn't bad at all. $37.95 I believe is one of the prices I found with free shipping. They are almost 4 feet long, by 2 feet, and 14 inches high. I like the idea of the canvas underneath, sounds interesting at least. Cost effective I don't know :( for c&c cages we spend $18 on the grids and then $20 on the sheet of coroplast and can get two cages out of that.
Here is what I was thinking though, as I can't do buy the guinea habitats. I am thinking of using a wire cutter to cut out a couple of grids, and extra coroplast to make a few two ways ramps. Then I can sand down any sharp areas for the piggies, and give them a kitchen YAH!!!
If I get around to it, I will post pics, but you have to check out the guinea habitats, they are so neat.
