Weeeellllllll........if they get toooo lazy, you can always get them a kitten or a baby bunny to be their very own pet!!!!!!

Actually, I think it is www.bunnybytes.com that has a great heavy-duty cardboard castle.... Your kids might like it...it has 3 levels and cut outs in the walls Daisy loves his, he's up and down and back and forth and has had it over a year....he has it pretty well chewed up...... He added a doorwall to the first floor, put in a picture window on the 2nd level and has taken out a non-load bearing wall in his remodeling efforts. Plus he gets to play the part of Errol Flynn in Robin Hood and comes swooping down the steps to jump on Marie or me when I'm walking by.... it's a great "toy". Anything to keep the kids amused......
