I'm going to make this short and I'll include pictures later, but as of yesterday morning I'm fostering a litter of 9 puppies until they're 8 weeks old (hopefully not much longer than that). Right now I have it set up so there's a giant kennel attached to an exercise pen with shower curtains under each and newspapers on top. I don't want to tape the papers down because that will make getting them up difficult, but they keep moving the papers and chewing on them and pooping on the plastic (or the kennel bottom), which kind of defeats the purpose of having papers and makes it even more difficult to clean up the papers since they're in pieces. Obviously some is going to get on there, but how do I minimize the poop/pee on plastic?
