These four lovely kitties were rescued by a shelter for homeless cats in Rio de Janeiro, Brazil. The one with the red collar was the first one to find a forever loving home.

This photo was taken when the rescuers arrived. "They were looking at us who landed on their place all at once, and they were very curious about us, the visitors."

A few seconds after the picture was taken, these little furballs started to climb on the rescuers' clothes and eagerly to get some playtime with them.

After Cora Rónai posted this photo, millions of cat lovers from all over the world were touched by these four beautiful kittens. "All I can say is that this is the picture that has brought me more happiness and good vibes -- from the sheer luck of catching them all looking so sweet to the joy of seeing the smiles they bring everywhere."
