There are two places where you can adopt an animal online:
Animal sponsorship is a cheap, unusual and worthwhile gift for animal lovers everywhere.
Sponsoring or adopting an animal has many benefits – both to the person who is taking out the sponsorship or adoption as well as the organisation and the animal being sponsored.
One of the main ways of adopting and animal is to sponsor an animal with WWF (World Wildlife Fund - click for their animal adoption site) 
So how does it work? Basically, sponsorship of an animal, whether it be a lion or orang-utan, an elephant , donkey, badger , tiger , rhino, rabbit or a rodent tend to be run by animal welfare organisations and charities.
Sponsorship can be done as a gift for someone for Christmas or their birthday.
With most sponsorships, you will receive a certificate to show that you have sponsored the animal and normally a glossy photo. Some organisations will send you a newsletter to update you on your sponsored animal or maybe a small gift – these tend to vary from sponsorship to sponsorship.
