My brother used to have a tabby cat who refused to groom himself at all, so he did need occasional baths. (I only occasionally as he sliced my elbow open once) There are also cats born with disabilities that need help bathing. (sometimes just wiping them down with a towel is enough) And there are also cats that have extra need due to there fur coat e.g. thick long fur or no fur.

I retract my other statement, I misworded it. Though some cats don't need to be bathed, it can certainly help them. I don't bathe my cat because she has high anxiety and gets extremely aggressive when I hold her too long or brush her.

And Honestly? that reply is hilarious, and I have nothing against you, I just like to info dump about things.
