Cats in Canada are at risk of worms from everyday life—outdoor exploring, hunting, or even contact with other pets. These parasites can cause weight loss, vomiting, diarrhea, and even serious illness. While the best treatments often come from veterinarians, many Canadian pet owners want to know: what are the best cat dewormers you can buy without a prescription?
Good news: there are a handful of over-the-counter (OTC) options available in Canada. Some are effective for roundworms, others for tapeworms, and some provide broader coverage. In this guide, we’ll break down the top OTC dewormers available in Canada, show you how to choose the right one, and help you keep your cat healthy and parasite-free.
Quick Picks: Best Cat Dewormers in Canada (No Prescription Needed)
- Panacur Granules (Fenbendazole) – Best Overall Broad-Spectrum
- Praziquantel Tapeworm Tablets – Best for Tapeworms
- DVL Worm Tabs (Piperazine) – Best Budget Roundworm Treatment
Buyer’s Guide: How to Choose an OTC Dewormer in Canada
Not all cat dewormers treat the same parasites. Here’s what you need to know before buying:
- Parasite Coverage: Some products only treat roundworms, while others target tapeworms or multiple types. Always match product to suspected parasite.
- Ingredients: Key actives include fenbendazole (broad-spectrum), praziquantel (tapeworms), and piperazine (roundworms only).
- Safety: Stick with well-tested pharmaceutical products. Avoid “all-natural” or homeopathic remedies with no proven effectiveness.
- Ease of Use: Granules mix into food, while tablets may require pilling. Pick what works best for your cat’s temperament.
- Follow-up: Repeat treatments may be required for full effectiveness, especially with roundworms.

FAQ: Cat Dewormers in Canada (OTC)
1. Can I buy broad-spectrum cat dewormers OTC in Canada?
True broad-spectrum prescription products (like Revolution or Drontal) require a vet. OTC choices like Panacur + Praziquantel can cover most common worms if used together.
2. Are “natural” dewormers effective?
Most herbal or homeopathic dewormers lack scientific evidence. They may support digestion but don’t reliably eliminate worms.
3. How do I know which worms my cat has?
Roundworms often look like spaghetti in stool or vomit; tapeworms appear like rice grains near the anus. For certainty, a vet stool test is best.
4. Can humans catch worms from cats?
Yes—certain worms are zoonotic, especially roundworms. Always wash hands, clean litter regularly, and treat infestations promptly.
5. How often should cats be dewormed?
Kittens: every 2 weeks up to 12 weeks. Adults: at least every 3–6 months, especially if they go outdoors or hunt.
Conclusion
When it comes to cat dewormers without a vet prescription in Canada, your best OTC options are:
- Panacur Granules for broad coverage (roundworms, hookworms, whipworms, Giardia).
- Praziquantel Tablets for tapeworms.
- DVL Worm Tabs as an affordable roundworm-only treatment.
Herbal and homeopathic remedies exist, but they lack proven effectiveness. For peace of mind, combining Panacur + Praziquantel (under proper dosing guidance) gives the widest OTC parasite control in Canada.
