get out of my garden!

dont get me wrong i love animals especially cats, but i could seriously commit murder where this cat is concerned. I dont actually know its name but i call it the ginger s**t. This cat terrorises my 16yr old cat Dudu and is so bold and brash will quiet happily come through our catflap and eat all her food and then joyously spray urine all over my kitchen.
Shouting and spraying it with water does not deter the little ginger s**t.

I'm sorry if i have offended anyone with my ranting and do actually feel bad for the cat, whos name is probably something a lot nicer like 'Lucy'. I just wish it would leave my Grannypuss Dudu alone, so she can sleep a lot easier at night.
