I have found flax seed oil excellent for cats and dogs if they do not mind some in there food. It does not have much flavour and has an endless list of properties. Excellent for aging animals as is is good for skin, fur, brain and especially arthritis sufferers...if animals take this when young they would probably avoid later life conditions. Once I lived with a dog riddled with arthritis and looked crippled when walking...the owner agreed I could give her this oil and she actually gain mobility back to a huge degree and had a lot better quality to life before passing. Oh also great for humans too!
