Tuna are deep sea creatures. There is, however, a good chance that at one point many washed ashore dead, allowing the cats to develop a taste for them.

Did you mean "open ocean creatures"? While tuna can dive 500-1000 meters, and while technically "deep sea" refers to >200 meters, I generally consider "deep sea creatures" to be those that live primarily/exclusively in environments with no light and high pressure, like on the sea floor (~3500m) or in trenches (down to ~11,000m).

But I could be wrong! Maybe a marine biologist or oceanographer can clarify? (Lemmy needs a Unidan, minus the ego and voting fraud.)

Either way, zero overlap with any feline habitats.
