I just put the first pets on the site. There are 2 dogs, 1 horse and 1 cat.
I also made a tutorial about making a real unicorn in Create-A-Sim.
Welcome to Lucky Sim Pets.
I'm still working on the site, but when it's done, you will be able to find all kinds of stray animals that need a new home. You could say this site is going to be a pet shelter for The Sims 3, with all kinds of dogs, cats and horses. So come back soon when I'm done.
