Questions & Answers

6 Customer Questions

Can I use both at the same time for my cat?
Answer by ChewyMay 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.

is this sage for kittens 7 weeks & up?
Answer by ChewyMay 20, 2021
This is safe for cats 8 weeks and older.

is the onward safe if licked by another cat. will it hurt the other cat?
Answer by ChewyMay 10, 2022
Do not allow your cat to ingest Onguard Plus, or get the product into their eyes. Proper placement of the product on your cat will minimize the opportunity for the cat to lick and ingest the product. Carefully avoid allowing the product to run off the side of the cat. Separate treated cat from all other cats and pets until product has dried.

Is the Capstar Flea Oral Treatment, 2-25 lbs + Onguard Plus Flea & Tick Spot Treatment for Cats (6 doses) 6 months supply 6 of the capstar AND 6 of the Onguard? Or is it 3 of each?
Answer by ChewyFeb 10, 2022
This bundle features a 6 tablet pack of Capstar as well as a 6 month supply of Onguard.

I have never considered flea tablets for my 2 cats. Was extremely frustrated with my flea invasion of both my cats and my home. Best product for fleas I have ever used! Slipped the tablet inside a teaspoon scoop of one of the very expensive canned cat food that I normally do not buy. I still use drops on the neck as a backup to help break the life cycle since Capstar only kills adult fleas. My cats are older and had no severe reactions to Capstar just a little dopey as usual after any treatment.

Smashed under cat food

The delivery was great. But the capstar was smashed under 37 pounds of cat food...ordered onguard wasnt delivered. Called customer service and the lady was the rudest I've ever spoken to. You'd think they could deliver 4 things. Glad I didn't order 8.

Capstar & Onguard Flea treatments

Capstar works great and as advertised. Onguard Plus works for about 2 weeks then starts losing it power to repel or kill fleas.

An effective One-Two Punch to fleas!

Together, these products have my Alison's fleas under control in just a few days. To make sure she gets the pill, I dissolve it in a touch of water, and mix it in her cat food and she takes it just fine. I am still using the Capstar pills every 3-4 days, but it's worth it.

Combined Special

I live in the south fleas get bad summer and fall time. I ordered this 2 for 1 price. Capstar always does the trick. The onguard was not as good as other spot treatments I have used. Capstar 4 stars on guard 3 stars.

Not working

Used both of these products on my two cats and they still have been itching there necks from fleas. I have no complaints about Chewy they are a great company but these two products are not..

Would not recommend

I bought these for all 3 of my cats. Let’s just say they made their fleas MUCH WORSE!! They were miserable. I went back to Cheristin for cats, it starts working fast, and I also bought Wondercide flea and tick Lemongrass scent, which works wonders too. I would not recommend this particular product to anyone unless you want more fleas!!

Capstar works

Ongaurd does not seem to work. Capstar tablets worked but ongaurd did not keep fleas from coming back

Grumpy Cat, happy cat

The cats don’t appreciate the wet back, but oral treatments are expensive. But both of these together work very well. I just wish I could have a separate Autoship every 3 months for this.
