I wondered the same thing! Have a search in the polls section and you'll find the sofa poll I started!!
I now let Harry on to the sofa - we much prefer if he asks first as he bombs us at 100mph otherwise - just to get the first lick in though
. To be honest I got fed up with trying to stop him from getting up there as he had learnt that if he got on the sofa he would be rewarded when he got off and he was milking the system
. In the end everyone wanted cuddles with him - we're all leather - so why not!? I've just had my evening full of sprocker cuddles and we both feel much better for the experience, so can it be so bad?
