kitty litter wet and dry (Washington DC SE)

Hello. My name is Anna. I'm looking for help getting some kitty litter and wet and dry food. I went to the pet pantry this month amd was told there was very limited availability of cat food. I don't know why people only seem to donate dog food like people don't have cats. I was only able to get I bag of litter which is gone. And I got 5 cans of wet food which is also now gone and no dry food. Please anything will help also I don't drive so drop off would be necessary. Thank you in advance.
