I've made a plan of how many girds I'm thinking about using to make my cage bigger if I do get a third boy. Will it be big enough for 3 grown males to happily get along in?
I dont understand your layout. Are the outside grids the walls of the C&C that stand vertical? Is the white space open area? Are the squares space fillers or cage floors?
Cleaning will be difficult with such a wide cage, perhaps a U shaped cage that equals out to 18-20 grid base?
Do you have space restrictions for the cage? I might be able to help better with more info.
There is a door Which is why I've left the big gap on all of the different ones. I do mange to clean their cage already which is the second one in my first post.
So something like just a normal 3x6 with like a 1x2 area cut out in the front of it for easy cleaning wouldn't fit then? I think a 3x4 with like a 1x3 loft would be plenty of space for three pigs though honestly if you cant do anything else.
