We have two Lionhead rabbits that we purchased from Pets martial about 4 years ago. They had, formerly, lived on a farm. About a month ago or more, (Ur) Highness began to become extra extra " vocal"- I mean like boisterous. We noticed her brother continues to be quiet -never speaking. He only maintains his strong silent stance and .annerism unless stomping his food or giving you gazes. He did start to ram the cage repeatedly, when the children put two large stiffed animals, the size of the rabbits) in the cage. Is He okay?
