just wondering if giving omega 3 supplementation in capsules is a good idea for healthy cats that are not on raw food? would there be any harmful effects?? I'm thinking of giving my scottish fold omega 3 for a) some dandruff whenever i brush him b) prevention of osteoarthritis that scottish folds commonly get also, ive been reading and have read up a little on needing to further supplement with vitamin E if i do supplement with fish oil? can someone elaborate more on that? thank you!!
