Cat Eye Medicated Drops and Ointments: Top 5 Vet-Recommended Options in Canada (2025) — Terramycin, Polysporin, Tobramycin, Vetericyn, BNP
Published on Wednesday, August 20, 2025
Therapeutic cat eye drops and ointments are specialized formulations — antibiotics, antivirals, and anti-inflammatory products — used to treat diagnosed ocular issues such as bacterial or viral conjunctivitis, corneal abrasions, and post-surgical care. In Canada these products are typically selected based on veterinary diagnosis, active ingredient spectrum, preservative profile, ease of application, and whether an ointment or drop is better for nighttime or prolonged protection. Pet owners prioritize safety, proven clinical performance, clear dosing instructions, and availability through Canadian pharmacies or veterinary clinics, while veterinarians emphasize targeted therapy, corneal health, and minimizing risk of resistance or delayed healing.
Top Picks Summary
Terramycin Ophthalmic Ointment
Terramycin is a long-standing veterinary ophthalmic ointment prized for its oxytetracycline-based broad-spectrum coverage and viscous formulation that stays on the eye longer than drops, making it a go-to choice for many feline practitioners. It holds its position here for dependability and clinical track record compared with more modern aqueous solutions like tobramycin and adjunct washes like Vetericyn, while typically commanding a mid-range price that reflects its veterinary pedigree and dosing convenience.
What the Research and Clinical Guidelines Say
Clinical guidance and veterinary ophthalmology literature support targeted topical therapy for many common feline eye conditions. Evidence comes from clinical case series, practice guidelines, and pharmacology studies that evaluate antimicrobial coverage, corneal penetration, and safety. While randomized controlled trials are fewer than for human ophthalmology, the accumulated veterinary experience and laboratory susceptibility data make many of these agents predictable and effective when used under veterinary supervision.
Topical antibiotics (for example, aminoglycosides and certain polypeptide combinations) are effective for many bacterial conjunctivitis and surface infections by reducing bacterial load and speeding clinical resolution when the pathogen is susceptible.
Topical antivirals and supportive therapy reduce clinical signs and recurrence in feline herpesvirus-related ocular disease; antiviral therapy is typically prescribed following a veterinary diagnosis.
Ointments (such as Terramycin-style formulations) provide prolonged contact time and a lubricating barrier, which can help comfort and protect the cornea overnight or when frequent dosing is difficult.
Anti-inflammatory eyedrops can control painful inflammation but are contraindicated or used cautiously with corneal ulcers because they can delay healing; this is why veterinary assessment is essential before use.
Laboratory susceptibility testing and culture are recommended in recurrent or nonresponsive cases to guide antibiotic selection and avoid promoting resistance.
Proper application technique and adherence to the prescribed regimen are strongly associated with faster recovery and fewer complications in clinical reports.
Frequently Asked Questions
Which cat eye ointment is easiest to apply and why Terramycin?

How does Tobramycin Ophthalmic Solution compare on seriousness and rating?
Tobramycin Ophthalmic Solution is prescription-strength and used for moderate to severe bacterial conjunctivitis and corneal infections, with an average rating of 4.6, offering potent aminoglycoside activity against many gram-negative pathogens.
Is Vetericyn or BNP available in this cat eye drop list?
No—this list includes only Terramycin Ophthalmic Ointment, Polysporin Eye Drops for Cats, and Tobramycin Ophthalmic Solution, and it provides ratings but no warranty duration, so warranty coverage isn’t stated here.
Conclusion
In Canada the cat eye medicated drops and ointments covered here provide a reliable starting point for treating common, diagnosed eye conditions under veterinary guidance. The five options reviewed — Terramycin Ophthalmic Ointment, Polysporin Eye Drops for Cats, Tobramycin Ophthalmic Solution, Vetericyn Plus Antimicrobial Eye Wash, and BNP Triple Antibiotic Ophthalmic Ointment — each have distinct roles: Terramycin is a long-used ointment for surface infections and lubrication; Polysporin-style drops offer broad topical coverage in a convenient format; Vetericyn Plus is a non-antibiotic antimicrobial wash useful for cleansing and supportive care; BNP Triple Antibiotic Ophthalmic Ointment provides multi-agent topical coverage; and Tobramycin Ophthalmic Solution is often the best choice among these for vet-directed treatment of confirmed bacterial infections because of its targeted potency and corneal penetration. We hope you found what you were looking for — you can refine or expand your search by product name, active ingredient, or intended use to find the exact vet-recommended option that fits your cat's needs.
