I tried this as my cat picked-up fleas when I had her stay in a Cattery for a week. After a couple of weeks or so, having tried another product, I bought this. I knew she wouldnít like being wet but she settled and I gave her a good massage all over, avoiding her head and eyes. After a quick blow dry she smelt lovely and her fur was very soft and fluffy. Iím not sure it killed all her fleas but seemed to help a bit. I donít think I will put her through the washing process again, as it did stress her a bit but depending on anyoneís catís temperament, if you needed to give it a clean I would recommend it.
