There has been a great deal of discussion on holisticat about flax
oil and whether cats can process veggie oils, too. There is some
evidence both ways. I really don't know what the scientific stuff
behind this is, so I cover all the bases and give Widgie a rotation
of oils, including Merritt Naturals Animal Essentials fatty acid
supp, and an organic flax oil supp. I have also used Derm Caps in the
past. I do see a difference in her fur and whether it's the flax or
the Animal Essentials which contains fish oils, I can't say.
The one oil I would not use is the cod liver oil because of the
danger of overdosing the A. Many of the pet supplement companies now
market fatty acid supps, so there are many to choose from. EFA's are
good for the heart and for asthma. There have been some recent
articles about the benefits of fish oil for the heart. But you'd want
to use a fish body oil, not the liver oil.
