I've been fighting a cold for the past two weeks and when I am home I lay on the couch covered up. I haven't been playing with Mina like I like to, but I think she understands illness. She never leaves my side for anything but a potty break. Last night she started purring and kneading the blanket around my shoulders until it was tucked up by neck and then she kept licking my nose. I think that is a good sign that she understands that meowmie is sick and can't lavish her with the normal amount of attention.
