Help Adopted Stray cats

There are a lot of cats just outside of where we live. Helping them by giving some food but we cannot afford to feed all of them as they grow. It is nice to have them spayed/neutered for their healthy growth but our finances can't accommodate it. Your help will be much appreciated as there is one cat who has broken legs after being hit by a car. The fur baby is ok but we think she needs medical help and that is where your HELP is much needed.
