yeah I think they defiantely need to have "thier own space" Even having Bella and Diggy together everday, day in day out she just gets sick of him sometimes...if thats the case and I see her really getting irritated I move the ottoman so Diggy cannot get up on the couch and Bella can. To give her some peace time. She totally enjoys it too! So as long as they can have away time from eachohter I think you'll be okay. Good luck and Happy sitting!
