......Well, I think the Aussies owe us Poms a few Tinnies
and of course that little Urn.
Please forgive the 'Off Topic' comment...........
Re. your question Ray - The holes are indeed just extra ventilation. As to replacing the the black fabric, I've had a look at my KN7000 and I think it requires a fairly major strip-down, to remove the fabric covered panel. However, I have a suggestion - you could try using a Lint Roller to remove the cat hair. They are normally used for removing fluff particles from clothing, after washing. If you are not sure what a lint roller is Ray, I expect 'The Gardener' will be able to help. The ones I use are manufactured by 3M Scotch.
