Hi, we are Francisco Trinidad and Indira Aburto. We asking for help to keep on feeding and hope to be able to fix or build a warm shelter for the colony of feral & stray cats that were lead to our yard by the lovely cat that made our house his home. Now we have about 12 cats and some recently born kitties, hope to get help so we can continue on feeding them and attract them to a warm shelter we plan on build at our yard with your help also they can be protected from a raccoon that has killed and ate several of them already.
