Warmest greetings! Please note that you created two identical threads, which is contrary to forum rules. Probably you did not realise that any thread by a new member which contains links is automatically sent for moderation by the system. I have now approved this thread, so it is viewable publicly.
I have deleted your duplicate thread and this one remains. I have looked at your website and was impressed.
I have no experience of buying an animal using a classified ad site. I have always got a pet from a shelter, or on occasions we were given an animal by a neighbour.
Getting a pet via a classified site is a bad idea: not only for the prospective genuine purchaser, but also for the seller. There have been quite a few cases in the press where pets have been bought for small sums by people who subsequently tortured and killed them. See, for example, the case of Nicolino Camardi: http://news.nationalpost.com/news/ca...month-sentence There are lots of others like that.
So I'm glad that you are publicising this issue. I really like your site, especially this page: http://www.four-paws.org.uk/sponsor-an-animal/
Many blessings to you for the work you are doing to help pets without homes!
