I would like to remind you that you are a cat. While I know cats will sample anything unguarded, this tea-thieving has now reached the point where you stuck your head in your Dad's tea cup while he was holding it (and gave him a shock when he tried to drink it). You've even developed discerning tastes. While the expression when tea is not to your taste is amusing I'm not supposed to know my cat takes tea, far less that she takes it milk, two sugars.
But tea and scones? Really? Most cats steal the cream and leave the licked scone behind. Stealing and eating the scone and leaving the cream in a sad, white, pat on the carpet? It did take me a moment to work out what it was, and a lot longer to clean it up.
I can't believe I'm saying this, but please eat your 'kills'.
