I had a few cats that simply went into ecstasy when I had hands with residues of bleach, not the perfumed one, just ordinary bleach, they would endlessly self-stroke against my hands, purring loudly.

Other cats simply ignored that smell.

Had the same experience many years ago when I used to swim regularly. The cat would not only love to lick and chew chlorinated hair, but also heavily snuzz my discarded towel.

As a child my cat would favour drinking water from our chlorinated pool rather than her water bowl. Interesting to read another anecdote about cats and chlorine. They say curiosity killed the cat, but maybe I’ll take the gamble and see if I can find an answer as to why!
