My cats love to lap up the remaining liquid after I finish a can of
sardines. Doesn't matter whether the sardines are packed in tomato, mustard
or no sauce. It's the vegetable oil in the can that they're after. I've
tested this by putting a bit of either canola or vegetable oil in their
bowl, and they love it.

There are some premium brand (Healthy?) dried foods that I would like to
feed my cats, but you know how it is; if it's healthy, then it must be
aweful tasting, so my cats refuse to eat some of those premium dried foods.
I think they might eat that stuff if I blended some vegetable oil in it.
Canola oil is quite inexpensive and is among the lowest in saturated fat.

I know that there are specialty cat products available that are beneficial
to a cat's coat. These products are oils that are labeled to be high in
omega-3 polyunsaturated fat. I know that canola oil has more omega-3 than
other commonly available supermarket vegetable oils. Only flax seed, borage,
fish and a couple other expensive specialty oils contain more omega-3.

Seems to me that vegetable oil is quite a treat for them. They're
indoor/outdoor cats and are not overweight. Is there anything wrong with low
saturated fat vegetable oil as a supplement to their diets?
