Hi, I am looking for some help please. My daughter inherited 2 male male rabbits that had been house rabbits. They have been living in their cages on our deck since May with occasional supervised runs around our garden. At the weekend we built a hutch and run for them in the garden and let them loose. No obvious toxic materials used in the construction or within the run. Today I found one deceased under the hutch and the other pretty unresponsive. I brought it into the house however it died a short time later. No obvious signs of injury or trauma and no signs of a disturbance in the hutch or run. Not sure what has happened to them. They were only fed hay, nuggets and the grass in the run area. Any suggestions please. I wouldn’t want to get her more until I knew what had happened. Thanks
