Which brush keeps the dense blue coat neat without over-fluffing the plush texture?

For a dense blue coat that’s plush-like a Russian Blue or British Shorthair-skip the slicker brush. That’s for fluffing out undercoats, which will ruin the smooth, velvety finish. Instead, use a fine-toothed metal flea comb or a rubber grooming mitt. The comb glides through without lifting the topcoat too much, and the mitt picks up loose hair while polishing the surface. Brush gently in the direction of growth, not against it, and focus on a few minutes daily rather than one long session. That keeps shedding under control without turning the coat into a fuzzy mess.
