I was wondering after reading posts on main coons and "weegies" greasy fur problems...if anyone has help as to solving the water resistance Siberian 3 layer coat! My boy on top of everything is hyper thyroid. I saw someone mention a mechanic degreaser thing...is that safe? I brush constantly, but Merlin needs help, blew out his knee, his hips are bad and HIGH as Siberians are jumpers ergo this causes a sway back and now his back hurts. He is on prednisolone, carbimazole and emergency buprenorphine (only when he cant move,) I put him through PT every day so his muscles stay toned. But his good days are great..his bad ..awful. he just has a trouble grooming and is soooo greasy!!!
