I've been off and on locked in my CB300 for the last month(allowed out once per week to paw off, and locked back up by the end of the night) and when my owner allowed me to take it off and paw last a couple days ago, I noticed a bit of an itch, but when I looked, I noticed some scabbing in the shape of the opening of the device. At some point, it has either rubbed the skin raw, or dug in enough to cause some minor bleeding. I'm not really sure what to do here, because I should be locked in the device (I do have permission to be out long enough for it to heal) but I fear this is going to be an ongoing issue that may get worse. So I suppose I'm looking for suggestions for alternative devices at this point, or possible solutions. Bear in mind, the CB3000 is actually a bit small for me, I'm pretty sure that's why all this happened.
