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.

Watch the fleas fall off!!!
You literally watch the fleas fall off your cat. I have a Persian kitty with a super fluffy coat and its been a nightmare trying to get rid of her fleas I purchased her with 😡. But this right here has been a blessing. She was really itchy for about an hour or two right after taking but it really works. Only thing I’d want more of is for it to last longer then 24 hours i wish it would last the life cycle of the flea
