My condolences on the loss of Tristan. *hugs* Promoting the Rescue Site seems a wonderful way to remember him. I'll click today in his honor.

As for the Rescue Site, I'm sure it's possible that it is a scam, but I doubt it. They do not ask for any personal information, and I have not got any spam emails that I could link back to them. And I have bought items from their sponsors without any problems (it is not necessary to purchase anything, I rarely do). As far as I can tell they get sponsors to donate food and such in return for advertising space and a countable audience for those ads (us).
