I need suggestions and/or pics on whelping boxes/cages. I have a pretty good size cage and was thinking about putting in a box half the size of the cage with a doggie door so mommy can get in and out. Can't really give her free roam of the house. My house is on the market and would like to keep them confined, yet safe, but at the same time...give mommy some space for herself when she wants a break. I work full time, but somebody is home at all times to take her out and give her several breaks from cage. Sorry this is so long, really need help in figuring out what to do. Thanks!! Appreciate any suggestions and or pics.
