Non toxic for humans. But citric acid is toxic for felines, it affects their nervous system🐈
Home sprays that are nontoxic to pets but are used to keep cats away from certain furniture or upholstery often contain orange oil (because cats don't like it), but it's not the juice of the fruit that's used (which has the acid). I'm sure this is an innocent mistake of them saying "citrus" without being specific.
