Oh I love these, thanks for sharing @richten1 
My old boy Walter is pretty set in his ways, but I’ve recently discovered him making a new noise, which is very specifically to prompt me to dry him with his favourite microfibre towel 
he will not accept a normal towel, it must be a very specific microfibre one that I use for my hair, and he gets all soppy and happy when I use it. He has this face I call the “cheese face” when he’s happy - his ears go wonky, his eyes half close, and he does this kind of grin with his fangs. Such a cute little weirdo!
