Mama cat & kittens (San ysidro)

This very sweet and docilemama cat and her 5 babies are in need of safe refuge, the mother is not aggressive at all, there are tons of raccoons in this area who will eat her kittens, in this community is already full of cats. I do not want to see these kittens as strays not to mention eventually, they could end up inbreeding with their Mom or sisters. So please, if somebody has the means to take in these cats they are homeless. The mother has a flea collar on, but I put that on her only to keep her free from fleas, which does not work, I am trying to be a good Samaritan. I try to do my part two be kind, but I have already helped her once with her last litter of kittens and it is just too much.
