I want to start the bonding process again with Poppy & Scratch probably next weekend. I'm thinking of setting their bonding area in our bedroom but I'm not sure what to do at night. The only thing I have to contain them with is Poppy's pen which I was going to wash down with vinegar first, then place it on a layer of newspaper with an old sheet on top. I was wondering about what happens at night because Poppy can lift the edge of the pen up when she's in a huff and what else do I need to put in the pen with them? The pens around 3ft x 3ft although I can configure it to be more of an oblong shape if it was up against the wall. Last time they just kept running in circles with Scratch pullling tufts out of Poppy so eventually she didn't want him anywhere near her!
