Can dogs or cats eat canned tuna?
Be careful read the fine print
The problem compound: mercury (accumulation) + unsupplemented nutrition. For: dogs & cats.
The cat-and-tuna cartoon is a nutritional trap: tuna-in-oil lacks taurine and everything else cats need. Treat, not diet.
Symptoms to watch
none acute; long-term issues if used as a diet
What this looks like when it goes wrong — most exposures stay mild.
