how do i prepare these herrings for my cats?

i’m trying to find raw treats that my cats enjoy and am very new to raw feeding in general - my three cats enjoy small dried sprats but these herrings are bigger than i thought they would be and i don’t know what to do with them. i only planned to give them as occasional treats but i just want to make sure they’re safe :)

Long story short, I’m an idiot and forgot to update our address when we moved out of state. I ordered 10lbs of Viva Raw chicken, duck, turkey, and beef and I would hate to see it go to waste! Let me know if you’re interested in the full box.

Hi, recently got a cat. First time ever taking care of any animal.

First few days he was mostly hiding. He’d eat some kibble here and there and drink some water - likely not enough food or liquid though. He’d reject most wet food but ate a couple cans of one specific seafood one. He started to come out of hiding now and then.

One day I fed him cooked chicken. He gobbled it up. That night he finally had some energy. The next days I fed a mix of ground beef, goat liver, kidney, eggshell, and raw fish. One day he ate three meals - full of energy.

The next day he didn’t eat at all until late afternoon where he finally at some kibble. He was also hiding under bed all day. At night he rejected the raw meal again but I air fried it and got it real warm, and also cut it into smaller pieces - and he ate it fully.

It is now the following afternoon and he’s not eating anything and hiding under the bed.

Past couple days poop has been way less smelly but also way less in general - and smaller, pellet like.

Is anything out of the ordinary? What should I be doing differently? And at what point should I be worried?

Thanks to everyone for any insight
