Just to hijack this a little, I've always been led to believe that white fleece blankets are the only thing supposed to be used at shows, and no sewed up bases are allowed, yet many of you seem to use them. Haven't there ever been any issues? How do you arrange the blankets in the pens for your cats? Up until now, I've just folded a double thickness fleece along the left side of the pen, but the litter in the back at the right, and then used the remaining space for food and water, but I've recently been told that food and water should go at the back with the litter, as folks have been known to drug this when passing by, and the blanket should be at the front. My main concern here is if my cat decides she wants to hunker down in the back of the pen. She'll then be in the litter, which isn't great. If she's close to the front, you also have the touching issue when the public come in. Some people say they make nests for their cats, but I haven't a clue how to make one of these. Any suggestions about nests/pen set up? What tends to work?
