Review: Get product, work good on my cats, stop the scratching and got rid of fleas, I recommend this product , I have 7 cats
Review: Cat Care I always go to this brand as it works so well. I especially like how quickly it works on eggs and is ok for the host. This eliminates any that might be brought into the house as other animals use the yard so keeping the home pets clean is important to health.There is no irritation on the small or large pets. The fur stays nice even with being exposed to the chemical. The animals show no side effects as the most important part of the treatment.

## Questions & Answers

**Q: How do you get the packaging open from Walmart?  It is in a hard plastic case. Cannot open!**
A: Did you steal this? The hard case is for anti theft. The product is taken out of the case at checkout. Take your receipt back to Walmart and have them take it out of the case!

**Q: LICE**
A: It worked on lice for the cats I put it on. One of them had a bad infestation. She’ll need more applied again. The life cycle is 3-4 weeks of a louse.

**Q: What is the difference between Advantage II and Advantage 9 Topical Solution.**
A: I dont have the answer but noticed the mention of Advantage 9. I bought Advantage 9 at the vets office. They said it killed fleas, ticks, and also wormed the cat. I paid around $25.00 for a 30 day supply. It works but i cannot find it anywhere else. Must be specific to vets offices.

**Q: Has product been updated to 2019? Also....dumb question, but how do you use it?**
A: I don't know about the update.  It is very easy to use.  Each dose comes in a little vial.  You take off the end and squeeze it on the back of your cat's skull where it joins his shoulders.  It's a place that he can't lick.  If he happens to somehow get some on where he does lick, he will leave it alone after one taste.  My grandson holds our cat and I put it on.  He doesn't seem to mind it at all.

*by H***I on 13 January 2026*

I use this regularly for mey indoor/outdoor cat. Whenever I notice she itches herself more aggressively, I know that it is time to give her a refresh. It definitely helped remove her mini fleas. I now use it once every month as directed.
