No catspam, please

I like to receive emails but I don't want any catspam. It is the cyberequivalent of fleas and will be dusted accordingly. I have not the slightest interest in:

• products to enlarge my tail
• ways to invest surplus Science Diet biscuits
• pyramid selling schemes involving used mice
• bulk/cheap orders of designer catfood, wildlife video nasties, radiators, dog deterrent powder etc
• deodorised cat litter that puts an end to embarrassing smells
• remaining bulk quantity of mice from failed investment
• promises of pictures containing 'loads of pussy' – in my experience there are never any cats in these
• computer-controlled catflaps
• British cat food available around the world
• guides on selecting the best clothes/furniture for shedding fur
• claw sharpeners that promise better shredded furniture
• keeping dignity in public – stop itching and scratching with discreet flea collars and oils
