Hester seriously hates bleach, but I've seen several people now say their cat likes it. I had no idea! Anyway, I'm resurrecting this thread because I made some cleaner that I think really does repel cats. It is essentially orange rinds soaked in vinegar. Then you strain out the orange peels and the resulting liquid can be used as an all-purpose cleaner. I have read that cats don't like citrus and all of my cats detest the smell. You could soak a garlic clove in there, too, for extra cat-repelling action.Some cats find bleach attractive - I've seen a kitten tripping on it - so in my view, NO bleach.
