Why do they like it so Much???

Maybe to a cat it smells like cat urine or something and attracts them?

I dunno why they like it, but our hospital cats LOVE to walk all over my freshly mopped floor at work. I used to just chase them across the floors (tracking them all up of course) and grab them, but now I just lock them up before I start mopping and let them out when the floor dries. LOL

I think it's the ammonia in the product. In the UK recently there have been a handful of cases where cats have died from drinking anti-freeze (the type used in cars) There is now a website about the dangers of Anti-freeze and to not leave it lying around or let them near it.
There was also a list of cleaning products in my magazine to look out for one including Dettol ( I don't know if you have that in the US?) which is a disinfectant that can be used for cleaning, cuts and grazes, on anything, and one cat dyed after licking it's owners laminate wooden floor after she mopped it.
So I would be careful and definately don't let them near the bleach or lick anything that has been cleaned with it. Silly cats!

Assuming we're all talking about Chlorine bleach (common household type) there is no ammonia in it. Actually mixing ammonia with bleach produces toxic fumes.

Chlorine itself is a gas at room temperature. Ordinary table salt (sodium chloride, NaCl) is half chlorine, and a simple electrochemical reaction with salt water produces chlorine gas easily. That same reaction produces sodium hydroxide (NaOH), and by mixing chlorine gas with sodium hydroxide you create sodium hypochlorite (NaOCl). When you buy a gallon of bleach at the grocery store, what you are buying is the chemical sodium hypochlorite mixed with water in a 5.25-percent solution. You're buying salt water that has been changed slightly by electricity.
