I once had a 4 level 2x4 (until October 06), which was very sturdy. Cable ties are the answer to keeping it that way! I also have solid chrome grids with much thicker metal than the colored painted ones, and that makes multi-levels very steady too.
You know what, I saw the chrome grids at Target, but I didn't get them because they were like $3 more...I didn't know they were sturdier.
I was wondering for those of you with multi-leveled cages, how steep (or not steep) are your ramps? I currently have a 2x4 C&C, and I've been thinking of adding a level.
Well I don't know how you would tell if a ramp is too steep by measurements, but what I do is literally look at it from a pig's point of view.
Once it is built, get down and look at it at about the height of one of your pigs. If it looks steep from that view then it will probably be too hard for your piggies to get up. My ramps are made of bent grids, and my longest ramp is made of two bent grids. I also have a wooden ramp made out of the top to a wooden hidy house. That one I think is kind of steep, but the piggies go up fine, so as long as it is secure and the pigs are comfortable with it, the incline shouldn't matter too much.
Also it's been kind of hard adding all the levels, because I need to have some spots open just for convenience to be able to get in to the fleece to vacuum it fairly easily. Right now I have it where I can get to almost everywhere, so I am very happy! lol
The reason I asked was because looking at the gallery there were only a few cages that had four levels, I didn't see any with five or more...hmmm...Maybe I can be the first one to have a 6 level piggy castle!! LOL! :crazy:
