Feral Cat Colonies

Picture on the left is Squeekers. He wants so bad to be loved but he is so scared. The resident males have been attacking him and we desperately want to get them all fixed however the SPCA is no longer fixing feral cats for free and we have no donations coming in at this time. We are struggling just to feed them. Please help if you can! The image in the middle and right side are two brothers who supposedly belong to a neighbor however they do not care for them.
