What I have found to be true about pets is that they sense how you are feeling without knowing or understanding what is wrong with you. I have been very sick the last couple of months with what I call the 'dizzy virus.' At times, when I am feeling dizzy, unbalanced and nauseous, my cats (2) will come to me and help me gain my balance back with their slow, graceful movement. They will then lie down beside me and make me feel at ease and better. Dogs and cats seem to know what we need, when we need it, even if we don't ask.
