I am so sorry but I am sure he will be fine.......there is another thread ontoday with someone who has just had a similiar problem and the op wwas today and went very well.I can imagine how you feel cos its all too much at once and its so sad that he was so unhappy when you left. Can you go and visit him tomorrow cos it helps and also to leave a worn shirt or something with them................this is a cat not a dog, isnt it? If its a dog I am told that visits make them worse. I am doubting its a cat cos you said he was howling.
anyone got a noose they can lend me
