I am in the planning stages of my cage for the K5. But I have some questions on design. I know that if it isn't designed correctly that it isn't much good. Should I design a halo or a buggy style with the tube running from the from floor of the a pillar all the way to the back pillar floor. This is going to be a "family" style cage to keep the young ones safe. The other question is how to properly seem the tubing together?? Do you always tie it together at a joint? Example is the halo style where do I join the two ends??
