Hello Zyan,
I have rescued many cats and dogs from the street and as you say its worth it. In El Salvador is common to see dogs and cats without a home, it makes me feel sad because I love animals and I would like to help all them but I can not always help them. Those situations are really fair because animals are most loyal that some humans. Many people think that If you give money to that kind of institutions who helps animals they steal the money or something similar but there are differents ways through you can see that it is not true. There are people who think that we have to help people and not animals and that is pathetic because frequently people who say it don't even help other people.
