We've had our piggies for a few months now and I want to get them a bigger cage. Currently they have a smallish one upstairs and then a large run (hexagonal, 4' diameter) that they get brought down to every afternoon to run around in. As they get bigger I'd rather give them more room permanently, I don't think the run would work full time as it is a flimsy tarp base with a separate wire surround and the hay gets everywhere. Can anyone recommend a large cage (we have a space which is approx 5' by 5' that we can use) which is all on one level (1 piggie won't climb ramps) and which won't lead to hay/sawdust all over my living room?
