My little black cat was an utter sod.
The most annoying thing not the launching herself from the top of the wardrobe onto my chest at 4am nor going to sleep on an open window frame and giving me conniptions in case she fell off was that for a black cat, her undercoat was grey, which meant she trashed both white AND black clothes.
Oh, and when she got old, she turned auburn. Made a change from dust coloured in the summer (she loved dustbaths, probably because she was functioning as a mini solar panel). Then I had to deal with black fur, grey fur and dark red fur.
She also went deaf and blind, but nobody else noticed for a couple of years.
'Why do you always bang your hand on the floor twice when you call the cat?'
'Umm, because she needs to feel where I am?'
'Why?'
'Because she can't hear or see me'.
'What? Don't be silly, of course she can - CAT! CATTY CATTY CAT-CAT! CAAAAAAAT! CAAAAAAATTTTTTTT [waves arms frantically whilst Cat sits in peaceful repose]- oh. Why didn't you say anything?'
'She has other senses, you know' [opens tin, watches for the moment the smell hit her nose, whiskers twitch and she immediately makes beeline for me, jumping up onto the kitchen chair without a single issue]
