I was just wondering if your Cavaliers play with toys or not. Mine aren't into toys but will play with it if it has treats inside it. They still do get quite a bit of exercise running around the house and garden. I think its just the way they have been raised. We adopted Lucy after her owners couldn't afford to look after her. She was spoiled as spoiled can be. I don't think her owners ever played or bought her any toys which explains her lack of interest in them. So do your cavaliers play with toys or not?
