Do you think pets (cats/dogs) know when we are sad?
Whenever I'm really upset, like having a full blown breakdown my cat sits with me and curls right up with me even if it's in the bathroom (on the floor) which she never goes in because she hates water. The other night I was really upset and she clawed at my door relentlessly until I let her in then sat with me in bed for hours until I stopped crying.
