When choosing a charity to donate to it can be difficult to decide which will make the best use of your money. In my opinion, it's also a good idea to donate to small local causes, as they are often the charities that need the money the most. When choosing a charity, you should also decide what is your main purpose.
When it comes to animal charities, you'll find charities that are concerned with the conservation of a certain animal or charities which are concerned with helping neglected and sick animals.
In most cases, whichever charity you choose, your money will likely be put to good use. However, this may not be the case for some organizations against animal cruelty, which could use your money to fund terrorist acts and negatively impact the economy. This film trailer https://animalrightsagenda.com
touches upon this issue.
This is why I feel smaller charities are a better fit for my donations because you can often see the impact of the money you donate.
