Desperately Needed:

WD40, or similar... The bedroom door, which has probably not been used since we had our previous guest litter (1995?), has developed a Sqweeeeeeeeeeee.... It is an excellent sqweee in its way - very suitable for hauntings, etc., i.e., very high pitched, very painful to listen to. Or so the human thinks. Cats - and kittens - and kittens - don't seem to notice!
