Masher's body is starting to failing her; she has cataracts on both eyes, and I rather suspect her hearing isn't what it used to be.
Last night Perp was doing her hugkiss routine: "Hugkiss donkey; hugkiss stove; hugkiss piano; hugkiss Masher." Mashy was curled up in her wee bed and Perp clambered over the side to deliver the goods and M lurched up and snapped. One small, single-drop-of-blood scratch and a broken heart. Hard way to end the day, man.
It's totally not the dog's fault, but she's out of the hugkiss circle now.
