One of the downsides of being a cat owner!
Could not understand why the letter 'i' was not working on my keyboard. Turned it upside down and thumped it a bit, to no avail. Started to look at ordering a new keyboard from Amazon and was just about to press the Buy button when I thought again. Went and got a stiff paintbrush to poke down between the keys and was HORRIFIED at the amount of cat hair I dug out!!! My 'i' is working fine now!! and I am sure the rest of the keys will thank me!
