I was singing (badly) as no-one else was in the house. The cat, shes not a lap cat. (Well only when she chooses). Was asleep in the room. She jumped up from her bed. Stared at me, then jumped up on the sofa and put her paw on my shoulder. I had to placate her and say its ok Im not ill. She thought I was ill. It was funny and so cute at the same time. Does anyone elses cat really react to singing?
