Help Stray Cats For Better Life

I live in a small town in Indonesia and There are many stray cats around my place that need help because people around don't really care. Sometimes there are people who throw them away. put them in a box and throw them in the side of street or sometimes they just leave them alone. i've been trying to find support from the local community but since I lived in a small town it's quite difficult and not very helpful. then I decided to make a project to collect funds because I don't know where I should ask for help.
Seeing them having difficult find food in garbage make feel sad so i feed them as much i can everyday. Many cats came to my place asking for food, but lately my situation has become difficult but I don't want to stop caring them because no one cares about them.
Also Some of them has skin problem but i can't take them to the vet because the cost quite expensive so i only give them treatment as best i can using ointments and sprays.

DETAILS ON FUND

* food/month = $50-70

* cat litter/month = $5-7

* other needs = $10

(Such as medicine etc because they has skin problem and sometimes they coming with some scars)

So for the money it will be help the cats at least for 6 months or more

my priority is to provide food for them so that they no longer have trouble finding food and If it's possible i also wanna built a little home outside so they can keep warm during cold weather

Thank you for reading my story. I hope you can help these stray cats because your help is their hope
