In memory of the feline who vibrated the most; the legendary Purrr of Rome.
Attila the Tattoo.

Apologies for the reflective quality of the picture and the obscure "in-the-know" reference. It's not a big deal. For those of you not in the know, Attila was a fine moggy of Roman heritage.
He Purrrred from duck til fawn and can be accurately described as a humming projectile (we know this from hearing him whizz past our ears as he was thrown around the room.....).
Alas, he fucked off never to come back to Leo but he remains in our memory now as the purriest (non-battery operated) pussy ever.
R.I.P.
