With raw meat you always have to be careful. If it's super fresh cats can eat fish/chicken raw. However if you're not sure about how fresh it is I'd definitely steam it because salmonella is a thing.

There's special raw meat (chicken mainly) sold as food quality for cats l where I live and that one I'm feeding to my cats raw: They adore it.

However when I just buy chicken in the supermarket I'm always steaming it before chopping off some pieces for my cats because I can't be sure about there maybe being bacteria or so that really should be heated to death first. There's differences in how much the stores and such have to pay attention when labeling something "food quality in raw" vs "food quality after properly heating up".
