Amazon Basics Flea Topical for Large Cats (over 9 pounds), 4 Count (Previously Solimo)

I have four cats, when one gets fleas, they all get them. I do not like using these products on my cats, but necessity required something better than what I was currently doing to keep the fleas away. With that said, this review was used with another product ( sold by another company).I used both an internal flea treatment and this topical treatment. Together the fleas were gone.I have one cat who is an older or SR cat. His body was more sensitive to the treatments. He has always been more sensitive even in his younger years. It takes him longer to recover from exposure to these treatments. Hence the reason for me not wanting to use the topical treatment.It had to be done and between both the oral and the topical the fleas were gone with one application. AND I have not let them go outside since the treatment ( I’m sure this has helped stop the infection as well)You have to remember prevention is worth a pound of cure. Extensive vacuuming of carpet and where they tend to sleep. Washing of their bedding. And Brushing out the fleas and their “nests” on each cat. The cat who had the longest fur needed the most attention with brushing out fleas.The application was easy to apply. The cats were not happy with the smell. I even had one cat cone over to me and hiss at me for his treatment! I don’t like them to be upset with me or to hurt them.. he was not happy and let me know.I prefer NATURAL treatments for my pur babies but this had to be done and I’m happy fleas are gone but I upset the kitties in using the product. It worked and I have gone back to my normal treatment. I don’t want fleas to build up a resistance to these flea treatments.
