I just found this on vetinfo.com
Question: Dear Dr. Mike, I am a new subscriber, but have had cats for many years. On another forum, I was chastised about using Lysol or Pine-sol to clean up linoleum flooring after litter box mishaps. I am curious about any studies of the health hazards of this type of product to cats. Of course, I do not allow my cats to walk in the area while I am cleaning up. When I use them, I sponge wipe the area with water afterwards and dry with paper towel.
Thanks for any info. John
Answer: John-
Veterinarians appear to be of two minds when it comes to these household products.
Cats do not process phenols well, which both products contain. Therefore, sufficient exposure to these chemicals could cause problems, including local irritation of the skin or softer mucosal tissues of the mouth or digestive tract. Liver toxicity may also occur.
Given this, some vets believe that these products should not be used at all where a cat might contact a surface cleansed with them. Other vets believe that if the surface is rinsed and dried, that the chance of sufficient exposure to cause a problem is very low.
I think that there is a case for both arguments, since I have read of a couple of accidental exposures to the cleaning solutions directly, usually due to inadvertent spills. On the other hand, in the entire time I have been in practice I do not remember treating a toxicity case from either product, making me think the potential for problems is pretty low. If you chose to use these products be careful, as you have been. If you want to use other disinfectants, it is probably best to be careful with them, too.
