I dunno. Looks to me to lack scales (some catfish apparently have scales). So my instinct is to go to Leviticus 11 or so
(Anything in the seas or in the streams that has no fins and scales . . they are an abomination for you . . you shall not eat of their flesh and you shall abominate their carcasses.)
(That is a paraprhase!)
After cleaning them up, that is. It's a bit of work ... guts, heads, skins, bones ... the cats get that.
