Just gonna throw my two cents in here.
I notice a lot of people telling you what to do in order to keep the grids, and I totally understand not liking them. I seem to have mastered the art of reinforcing it so it's sturdy enough, but still I'd like to do something else if I could. I mostly hate how ugly coroplast is, it just looks cheap and ugly to me personally, but I deal with it for the sake of the pigs of course. Right. I also think the cage is ugly, on top of not very sturdy, on top of having to zip tie things together to make them safe...I personally find the whole mess annoying, and I can't wait to use the grids as shelves...and build a permanent hutch that's nicer to look at and easier for me to clean! As well as comfy and safe for my piggies!
There are a lot of ideas out there for alternative cages though, it just takes a little more imagination and dedication. Plexiglass, wood, metal, etc. If I ever have piggies later in life, I want to build some variation of a plexiglass modern looking cage myself.
