Desi said "eh" to tuna, but loves sardines. Ick to the tomato sauce, though, he'll take his plain.
FWIW, he gets probably a third of a sardine in each meal. After he's gone through a can of sardines,
I'll boil up a few eggs, & he'll get 1/2 an egg chopped up on each meal.....when those are gone, it's
back to sardines for another few days. He seems to like the variety.
