Think of the expedition as the juggernaut's trimmer sibling. It keeps the emphasis on activity, with plenty of restful spots worked in, and a 50 inch bridge ties the scratching pole to the rest of the structure. That bridge quickly becomes the hangout, the spot everyone claims.A leaf shelf sits partway up the scratching pole, and it does more than add a perch, it means your cat can move through the whole condo without hitting a dead end. Open routing like that keeps cats from feeling cornered and keeps the peace when there is more than one of them. It comes in versions for 16 and 24 inch stud spacing.
