When I first joined PT I remember starting a thread saying that I had sent a Blue Cross leaflet anonymously to some neighbours who always, but always had kittens being produced left, right and centre.

Walking by the house today I noticed a Blue Cross sticker in their window and it dawned on me that for at least 2 years there have been no signs of their cats producing litters.

So being an interfering old busy body isn't always a bad thing
