The German Rex's curly coat requires a different grooming approach than that of a standard short-haired cat. The absence of guard hairs means the coat is composed entirely of soft, fine undercoat that curls and waves rather than lying flat. Aggressive brushing with stiff bristle brushes or wire slickers can straighten the curls, damage the delicate hair shafts, and irritate the skin beneath. The goal of grooming a German Rex is gentle maintenance, not the thorough de-shedding that denser-coated breeds require.
A soft rubber grooming mitt or a fine-toothed silicone brush is the ideal primary grooming tool for this breed. These tools collect loose hair through gentle friction without pulling on the coat or flattening the curl pattern. Stroking the coat with a grooming mitt also distributes the natural skin oils that give the German Rex's fur its characteristic sheen. Most German Rex cats enjoy the sensation of being groomed with a soft mitt, which makes the process a bonding experience rather than a chore.
A fine-toothed metal comb with rounded tips can be used occasionally to check for tangles or debris, particularly around the ears, belly, and the backs of the legs where the coat may be slightly longer or denser. Run the comb through the coat gently and in the direction of hair growth. If you encounter any resistance, stop and work through the area with your fingers before continuing. The German Rex's coat rarely mats in the way that long-haired breeds do, but small tangles can develop in areas of friction if left unattended.
Bathing is occasionally necessary for the German Rex, more so than for most short-haired breeds. Because the coat lacks the guard hairs that normally wick oils away from the skin, the German Rex can develop an oily or greasy feel to its coat if natural sebum accumulates. A gentle cat-specific shampoo used every few weeks to monthly keeps the coat clean and the curls defined. After bathing, pat the coat dry with a soft towel rather than rubbing, which can frizz and disrupt the wave pattern. Avoid using a high-heat blow dryer, as the fine coat and exposed skin are sensitive to heat. A low-heat or cool setting, held at a distance, is acceptable if the cat tolerates it.
