I have a 6 month old Ragdoll. He will not stop purring. I understand that cats purr when they are happy, affectionate, or content and that it is supposed to be a good thing. But he purrs even when I am not petting him, he purrs when he is scared, he purrs when he is just walking around. He never ceases. The purring is louder than normal purring too, it keeps us up at night. Do you think there is anything wrong with him? Also will he grow out of it? He has already been neutered. I have had kittens and cats in the past before and I have never seen this. They purr when stroked or petted only. Please help. :O/
