if the lady is a cat-lover , surely she'd understand your request for a 'home' burial ?
on a side-note , many moons ago , a cat of mine went missing
she was found dead in the garden of (unbeknownst to me) the local cat killer.....(gardening enthusiast)............this cunts method was to put them in a wheelie bin half-full of water and let them get exhausted and drown
believe me when i say it took a lot of persuading for me not to go round his house and pour lighter-fluid through his letterbox.
i had to content myself with throwing a large tin of gloss paint (lid loosened) through his living room window........and
sodium chlorate all over his precious plot (which still today looks like the Badlands).
he died of a brain hemmorage a couple of years later
gotta love Karma
