WORKS FAST!

This stuff is amazing. My cat had never been outside but my dog goes out. She had a cluster of fleas on her face. Gave her one pill and within a hour no more fleas! Got some for the dog also, same results! She was knocking everything off the top of my fridge, so she won ( see pic) LOL. I set her all comfy :)

Quick fix

I use this for my own cats and ferals when we need a quick fix before treatment. I starts killing fleas within an hour. Then you need a topical medication from your vet. This will always be my go to. I’ve bought several boxes and will keep buying them.

Capstar flea medication

Let me tell for someone who tried about everything you can think off I waisted so much medicine on my cat and nothing was working and finely my cat was happy again she was get this big ball from the flea bite her and after a day or so my cat was so lovable and happy she finely stop scratching to a the lovable cat she was before when I first got her. So this a very good product the only complain I had was it took over like 3 weeks for it to get here but other than that I am very happy costumer.
