Basically, I'm going to take the wire top off their current cage and put an under-bed storage bin right beside it with a ramp to go between the cage and bin. I'm going to then put some wire shelving around the entire thing (it's adjustable shelves so I can make them fit whatever the lengths are). Are there any really basic issues I'm missing with this? And any suggestions for making a ramp?
Not tried them myself but maybe a grass mat might work as an alternative. obviously not rigid but better than a fence edge and gives them some traction too but as i said it depends what they need to get over and how high it is.
Something like this
Also, with this addition my two piggies will have about 14 square feet. Will I still need to give them floor time with this much space, or will they be able to get enough exercise in the cage alone?
