Rats: no eating worth mentioning & debatably hygienic.

Flying rats: tasty. Unless they're London (or other city pigeons) rats. In which case sharpen the beaks & use them as pencils...

Tree rats - Far too many of the little bastards, & good eating too! Ignore Hawk, who is going against his predatory instincts (if in doubt, cry "Ted Nugent for Prez!"), kill them (humanely) & eat the little fuckers!
