Questions & Answers

6 Customer Questions

Can I use both at the same time for my cat?

Answer by Chewy • May 29, 2021
Capstar can be combined with Onguard Plus Flea & Tick Spot Treatment. If you are currently administering a monthly flea infestation preventive and your pet still gets fleas, you may administer Capstar treatments daily, as needed, for quick relief against a flea infestation. Capstar may also be used with flea shampoos, as well as heartworm preventives, antibiotics, vaccines and de-worming medications.

This was a preventative step. I don't think my cat had fleas so I cannot really tell how effective the treatment was. I thought the order process and delivery time were both excellent.

The Onguard flea meds didn't do the job for my 3 inside cats. They were still scratching 2 weeks after I applied it. It may work differently on other cats but the fleas on my cats must be real warriors. Chewy has made it right and I've ordered a different brand. Hopefully it will have better results.

Although the drops work to kill ticks once the bite it hasn't repelled them. The pills are a waste of money too. Both my dogs have had fleas the entire time. It hasn't helped. Will not purchase either one again. Had better luck with Capaction.
