It works great for up to 8 months and I don't have to mess with the drops every month.

I think this company is wonderful especially for myself who is a small res ue

Great to work with, and the seresto collars for my cats at their sanctuary are the best!

I bought this because the price is very good as compared to buying it locally. I have used one of these collars before that I bought locally and really did keep the cat flea free. It did not include the reflectors that can be snapped onto the collar, and it does not have the loop on the collar to put the excess end of the collar into, therefore leaving a few inches of the end of the collar unsecure. Hopefully it stays in place.

Our fleas and ticks became immune to the stand-by drops and I found Seresto. It's a product that absolutely works, and for eight months! We have six cats and flea and tick control gets expensive. It was worth it but it had to be planned for in advance. Now I've found and save $20-$40 for each collar and no ticks or fleas, no trying to catch six cats once a month, trying to remember to do it, it's a win/win.
