Hi NoahsMommy,
You are doing the right thing by starting to bathe Noah at an early age. Eventually, your cat will become used to taking a bath and will also eventually get used to being brushed. Noah may never actually welcome these events, but he will become tolerant of them.
Do you clip Noah's nails? If not, you might want to introduce this bit of grooming to him as well, while he is young. When I clip Bo's nails, I always give her a treat afterwards so she knows I appreciate how good she's been. (Bo LOVES to be brushed!) Cats can be trained to tolerate bathing and grooming, especially if they know they will get a treat afterwards, be it food or lots of attention from their humans.
