Referring to above post, yes it does have certain chemical compounds that are also present in cat wee.
Not a problem for washing out your litter trays - at all - in fact it helps to reinforce the idea that the tray is the place to go.
Obviously, cleaning a place where an accident has happened has to be done differently - solution of biological washing powder or liquid is advised here plus maybe a followup of white vinegar.
Be very very careful of what you use around cats - many common disinfectants etc are poisonous (and won't stop the cats peeing there again).
Bleach for trays - yes!
