Fund raising for 3 orphan kittens

Hey guys!
On the 6th of August we found 3 newborn kittens outside a building in a box. They were about a day old, their mom was not around and it looked like they were thrown out by the people living in the building. It gets extremely hot in summer in Riyadh and these babies were literally screaming because they were left outside! My sister and I saw this and decided to bring these kittens home. They have been with us for the past 10 days and they are the most adorable little things we have ever seen!
We have tried reaching several shelters but they refused to take these kittens in because they were very small. So, we decided to take care of them and provide a loving home for them. However, it's difficult for us to be able to pay for the upcoming medical expenses of these babies (like vaccinations, vet check ups and neutering) as my sister and I are still studying. We will be very grateful and happy(and so will these babies) if you donate some money for us to help provide the necessary care for these fur babies.
