Yup. I’ve seen markets in SE Asia with stalls selling fried rats (sometimes on a stick), as well as lots of their kin running around.
Catching and frying rats in Cambodia:

You can see them in markets in Thailand, Vietnam, etc. Fried, barbecued, cooked to soup, etc. Mmm mmm good!
Honestly, I see no real difference between a rat and a squirrel..............
