Thanks iheartruby - Claude is my favourite cat out of the four and I have turned a blind eye many a time, but now he is doing is repeatedly on furniture (antique!!) and when I am at work all day the stain and the smell lingers, if I am at home I find myself checking all his places constantly.
He gets lots of attention from me and my daughter, but my husband seems to scare him, he is the biggest cat of the four but just lately seems to be behaving like a pansy.
The youngest of the cats is not quite a year old and is the product of my eldest daughter's broken relationship, so we haven't had him as a kitten, but he loves all the other cats and as far as I am aware is not a bully, but Claude really does like watching out of the window, mainly bird watching!!
