Cat Wormer Without a Vet Prescription: Safe Options That Actually Work
Many U.S. cat owners look for a cat wormer without a vet prescription because vet visits can be expensive, inconvenient, or simply unnecessary for routine parasite control. The good news: several trusted, vet-strength worm treatments are available without a prescription when purchased from reliable online suppliers.
Two of the most effective options are Bravecto Plus for Cats and Drontal for Cats. Between them, they cover the most common intestinal and external parasites affecting cats in the United States.
This guide breaks down what they treat, why they work, and how to choose between them.
Why Cats Need Worming (Even Indoors)
Indoor cats don’t get a free pass from parasites. Cats can pick up worms through:
- Fleas (tapeworm is extremely common)
- Ingesting insects
- Contact with contaminated surfaces
- Rodents entering the home
- New pets or visiting animals
- Symptoms may be subtle, so most vets recommend routine deworming rather than waiting for signs.
Common worms in U.S. cats include:
- Tapeworm
- Roundworm
- Hookworm
- Lungworm (less common but possible)
The right wormer removes active infections and helps protect your home and other pets.
Best Cat Wormers Without a Vet Prescription
Two proven, safe, broad-spectrum options stand out for U.S. pet owners:

2. Drontal for Cats
Roundworm + Hookworm + Tapeworm
Drontal is one of the most widely used worming tablets for cats worldwide. It doesn’t cover fleas or ticks, but it targets intestinal worms directly, including tapeworm — something most spot-ons do not handle.
What it treats

Indoor cats with tapeworm risk from fleas, and households needing an affordable, targeted intestinal wormer.
Which One Should You Choose?
If you want complete coverage and don’t want to think about dosing every month, choose:
✔ Bravecto Plus for Cats
Ideal for:
- Flea problems
- Tick exposure
- Mosquito-heavy regions (heartworm risk)
- Cats that hate tablets
- Owners who want “all-in-one” coverage
If you mainly need intestinal deworming, choose:
✔ Drontal for Cats
Ideal for:
- Tapeworm issues
- Roundworm or hookworm infections
- Budget-friendly routine worming
- Indoor cats exposed to fleas
Many owners use Bravecto Plus regularly and Drontal as needed if tapeworm ever reappears.
How Often Should You Worm Your Cat?
General guidance for U.S. homes:
- Bravecto Plus: every 2–3 months
- Drontal: every 3 months, or whenever you see signs (e.g., rice-like tapeworm segments)
Kittens often require more frequent worming until 6 months old.
Signs Your Cat May Have Worms
Even if you don’t see visible worms, watch for:
- Weight loss
- Dull coat
- Rice-like specks around the anus (tapeworm)
- Vomiting or diarrhea
- Increased appetite
- Scooting or irritation
When in doubt, treat — worms rarely go away on their own.
Final Thoughts
Finding a safe, reliable cat wormer without a vet prescription is easier than it looks once you know which products actually work.
Bravecto Plus for Cats gives you broad-spectrum parasite control in a single applicator, while Drontal for Cats provides fast, proven intestinal worm removal. Depending on your cat’s lifestyle, you may use one or both throughout the year.
