Dog, cat food and cat litter (San Diego California)

In Need of some decent brand salmon dry dog food (pics are what I normally get) and a few bags of the crystal cat litter. It works the best for us. I have two indoor cats and a Havanese dog. Also need some gas to get to Dr appts. If anyone could help me out that would be appreciated. I live in a RV full-time normally staying at the Thousand Trails Parks most the time but they have limited availability. So I may be out on the streets somewhere after Tues.😔 please help.
