No I totally disagree with offering anything like pets on a site like this. There are lunatics out there that will take a pet and how on earth can they be home checked. There is enough abuse of animals out there without offering them to "anyone" for free. There are rescues out there for all types of rescues including rabbits and fish. Please make it against the rules to do so. Other sites like e-bay do not allow this. I have never seen any on other freebiy sites eg the freecycle sites, its just not ethical. Here is another site
www.petsireland.invisionzone.com as well as the
www.irishanimals.ie site are great.
