Where to get cat litter/food for free? In a bit of a pickle

Okay so basically a bunch of stuff happened and the long and short of it is that I have no money whatsoever right now.

I can’t afford food or litter for my 2 cats, Mylo and Maggie. (My entire reddit profile is basically them as they’re my everything lol)

I’ve contacted some rescues and shelters near me but they didn’t have anything available.

Tomorrow I will be contacting food banks to see if they have cat food available. But I’m just worried if they don’t. What should I do?

I have 2 pouches of cat food left and that will feed them in the morning but after that I just dunno what to do and I’m freaking out.

Is there anywhere that will give me some free cat food or cat litter??

Thanks!
