I can get it locally for only US$1.00 per 15 ounce (425g) can. It has a
light tomtato gravy, but no vegetable oil. Like canned salmon, it includes
bones that are somehow softened by the heating-canning process. Contains
lots of protein, calcium, and fish oil. Comes from Chile.

Just wondering about its magnesium content. Keep in mind that a jack
mackerel is only a 11" (28cm) fish that doesn't live for anywhere near as
long as a tuna.

This is a cooked human food?  I would only give it to a cat as an occasional
treat, not as his regular diet.  Cats have very specific nutritional needs very
different from our own.

Could have some as a treat once in a while.

Lauren, do you supplement omega-3 fatty acids? If so, how?

Personally, I feed my cats the occasional meal of canned oily fish:
salmon or mackerel. Cheaper and more available than uncooked fish; more
palatable; less prone to being contaminated by flukes (since we eat
wild-caught Alaskan salmon in my household).

Yes, cooked human food.

Gasp. The horror.

To the OP: the tomato gravy would make me hesitate (what-all's in
there?), and might turn your cats off too. Try to find the stuff packed
in water which should be just as cheap; rinse it a bit to remove excess
sodium before feeding.

Don't feed much at a time (the fat can cause the squirts in animals not
used to it) and don't feed it too frequently (who knows why fish
sometimes instigates urinary troubles but it does).

I would be hesitant about feeding with any regularity a specific fish.
Mackerel can be a high source of Omega 3 fats, but it can also be high in
mercury and PCBs depending on where it was caught.

If you want to get long chain fats in your cat then consider a supplement
where the fish oil has been refined and microencapsulated to aid in
digestion and prevent stomach upset.

Also at that price for a can of fish I would be highly suspect of the
quality and cleanliness of the production facility!

Right.
Fish with highest mercury level :  tilefish, swordfish, mackerel, shark,
white snapper, tuna.
Lowest:  salmon, flounder, sole, tilapia, trout.
USFDA, may 2001.

I give them once in a while sole and smelts.

I do use whole body fish oil in capsule form.  I'm highly allergic to fish so I
can't feed my cats any fish.  My husband handles the fish oil :)

They say mackeral can be high in mercury and other contaminants, I guess
depending on the source, but I don't think an occasional meal is going to hurt.

I get it for as little as $ .75 (dollar stores and such).  I've never offered
it to my cats but my dogs get it as a change on their diet once every 2 weeks
or so.  The dogs love it.  The cats haven't shown any interest in the dog's
bowls when it's served.  Maybe they just know they're supposed to eat their own
food, but it may be that it doesn't appeal to them as well!

Check the ingredients. If it has onions in the gravy, do not feed it to your
cat.  Onion can cause a dangerous anemia in cats.

.... and possibly ciguatoxin.

One of our vets was an emergency and critical care specialist for about 10
years.  He was presented with several cases of severe diarrhea and vomiting
in cats that were recently fed mackerel.   One case involved two of three
cats in a household - the third, asymptomatic cat, did not eat the mackeral.

At the time there was no test to definitively diagnose ciguatera poisoning,
however, the symptoms in the cats closely resembled ciguatera poisoning in
humans.  He encountered a few other cats over the years with the same
symptoms who also recently consumed mackeral - that's why he suspected
ciguatera poisoning.

There's no way to detect ciguatoxin in fish -- and there's no way to destroy
it.  Cooking, freezing and canning have no effect.  So the best way to
reduce the risk is to avoid the fish that are known carriers of ciguatoxin.
Also, the larger the fish, the higher the concentration of ciguatoxin - big
fish eat little fish contaminated with ciguatoxin -- and bigger fish eat
those fish and so on.  The highest risk is in fillets because they can be
cut from 100-pound King Mackerals.

I would avoid feeding raw fish to cats altogether.  Some fish contain
thiaminase - which is an enzyme that destroys thiamin (vitamin B1).  Cats
are very susceptible to thiamin deficiency because of their high requirement
for thiamin.   The risk for thiamin destruction exists only when fish is fed
raw -- cooking destroys thiaminase.

Good luck.

Phil.
