Tuna can be fatal to cats and is not something to be fed to them. I use the
broth from tuna to administer herbs at times or for a special treat.

The human variety of tuna fish contains an enzyme that destroys vitamin B1
(thiamine). Cats who regularly eat tuna can develop a vitamin B1 deficiency,
which results in neurological symptoms like dilated eyes, loss of
equilibrium, seizures and death if this vitamin is not replaced. The
scientific name of this disease is polioencephlomalacia.

Clearwater veterinarian Richard Brancato said that though most domestic cats
do enjoy fish, feeding them a diet of only tuna can cause serious disorders.

Although it is high in protein, tuna lacks sufficient amounts of certain
amino acids, mainly taurine, to maintain feline health. There is
insufficient calcium to balance the phosphorus; the ratio in canned tuna is
1-to-14.8. This results in bone disease.

Many essential vitamins such as A and most B vitamins are also lacking,
Brancato said. A common disease in cats fed a mainstay of canned tuna is
steatitis, or yellow fat disease, an inflammation of the fat tissue in the
body due to a deficiency of vitamin E.
