I am wondering if people out there give their cats coat supplements. Diddo and KittenKiya are both showing some dry skin on their backs near their tails. I was thinking of adding some Omega 3 fish oil supplement to their diets. Does anyone use the stuff? How much should I give them? Their coats look shiny and beautiful, they are not sick, no sneezing, coughing, watery eyes, no ear mites, no fleas. Just some dry skin. Any suggestions would be gratefully appreciated.
