Product Description
Barrier Topical Solution (Purple Box) is an FDA-approved, prescription-only monthly spot-on for cats and kittens 9 weeks or older, weighing 9.1 to 18 lbs. Each 0.8 mL tube contains 10% imidacloprid and 1% moxidectin, the same active ingredients as Advantage Multi for Cats. One monthly dose prevents heartworm, kills adult fleas, treats ear mites, and controls roundworm and hookworm infections in cats.
Benefits
- Prevents Heartworm Disease: Moxidectin prevents Dirofilaria immitis larval development into adult heartworms when applied once monthly to cats.

- Treats Ear Mite Infestations: Treats and controls Otodectes cynotis ear mite infestations in cats with a single monthly topical application.
- Treats Roundworms: Treats and controls Toxocara cati intestinal roundworm infections in cats effectively with each monthly dose.
- Treats Hookworms: Treats and controls Ancylostoma tubaeforme intestinal hookworm infections in cats effectively with every monthly application.
- Same Ingredients, Better Value: Contains the same active ingredients as Advantage Multi for Cats, offering equivalent five-in-one parasite protection.
- Easy Twist-to-Open Applicator: Features a twist-to-open cap that breaks the seal without removal, making monthly application simple and mess-free.
- Made in the USA: Manufactured and packaged in the USA from a registered FDA facility, ensuring quality and regulatory compliance.

How to Use
Directions for Use
- Prescription Required: US law allows this medication only when a licensed vet prescribes or authorizes it.
- Open the Tube Correctly: Hold the tube straight, break the seal by twisting the cap, and keep it attached while applying.
- Apply at Neck Base: Separate the fur at the base of the cat's head until the skin is clearly visible before applying.
- Squeeze Entire Contents: Squeeze all the contents onto a single exposed spot on the skin, avoid rubbing, and allow it to air dry.
- Lift Tube Before Releasing: Remove the tube from the skin before releasing pressure to avoid drawing the solution back into the tube.
- Apply Once Monthly: Give this treatment every 30 days to keep continuous protection against heartworms, fleas, and parasites.
- Prevent Post-Application Licking: Keep the cat from licking the application site for 30 minutes and separate pets until the area dries.
- Test for Heartworm First: Test all cats for existing heartworm disease before beginning a heartworm prevention protocol with Barrier for Cats.

Additional Information
Precautions
- Minimum Age and Weight: Do not use in cats under 9 weeks of age or weighing less than 2 lbs.
- Sick or Underweight Cats: Never apply Barrier to sick, debilitated, or underweight cats regardless of their age or current body weight.
- Breeding, Pregnant, Lactating Cats: Safety has not been established in breeding, pregnant, or lactating cats; always consult your veterinarian before use.
- Geriatric Cats: Use with caution in older cats that may have undiagnosed underlying health conditions and consult your veterinarian first.
- Licking Prevention Critical: Accidental ingestion or licking of the product may cause hypersalivation, tremors, vomiting, and decreased appetite in cats.
- Bathing Efficacy Not Evaluated: Effectiveness against heartworm after bathing has not been evaluated; avoid bathing the cat close to application time.
- Keep Children Away: Children should not come into contact with the application site for at least 30 minutes after applying.
- Eye Irritant for Humans: Avoid eye contact, wash hands thoroughly after handling, and flush eyes with water immediately if accidental contact occurs.
Possible Side Effects
- Hypersalivation: Excessive drooling can occur if the cat grooms the treated area; applying at the head base reduces licking access.
- Vomiting and Decreased Appetite: Vomiting and reduced appetite have been reported when the product is accidentally ingested through self-grooming by cats.
- Tremors: Neurological tremors have been reported following accidental ingestion of the product; contact your veterinarian immediately if this occurs.
- Application Site Reactions: Stiff, oily hair at the application site may appear temporarily; this is cosmetic and does not affect product safety.
- Human Adverse Reactions: Human exposure may cause headache, dizziness, and skin redness, burning, or tingling; seek medical attention if these symptoms occur.
Storage Information
- Store at Cool Temperature: Store between 4°C (39°F) and 25°C (77°F); avoid exposure to excess heat or cold at all times.

Frequently Asked Questions
Q1: What does Barrier Topical Solution (Purple Box) treat and prevent in cats?
Ans: This is a monthly spot-on treatment for cats that prevents heartworms, eliminates adult fleas, treats flea problems, controls ear mites, and handles roundworm and hookworm infections in kittens and adult cats over 9 weeks old.
Q2: How does Barrier for Cats compare to Advantage Multi for Cats?
Ans: Barrier for Cats contains the same active ingredients as Advantage Multi, 10% imidacloprid and 1% moxidectin, at identical concentrations. Both are FDA-approved monthly prescription topicals offering equivalent five-in-one parasite protection, with the primary difference being the brand name and price.
Q3: How do the two active ingredients in Barrier for Cats work?
Ans: Imidacloprid targets the nervous system of fleas, causing paralysis and rapid death within 12 hours of application. Moxidectin is absorbed into the bloodstream after topical application, where it disrupts the nervous systems of heartworm larvae, roundworms, and hookworms, preventing development and eliminating existing infections.
Q4: Can Barrier be used in cats weighing more than 18 lbs?
Ans: For cats over 18 lbs, an appropriate combination of Barrier tube sizes should be used to reach the correct dose, as directed by your veterinarian. Never use a single Purple Box tube alone for cats exceeding 18 lbs without veterinary guidance.
Q5: Is the monthly cat spot-on safe for pregnant or lactating cats?
Ans: Barrier for Cats has not been tested for safety in breeding, pregnant, or nursing cats. If your cat is in any of these stages, talk to your vet before starting parasite prevention.

This Shipping Policy explains how orders are processed, shipped, tracked, and delivered.
1. Shipping Origin and Fulfillment
Orders are dispatched from our U.S.-based fulfillment center. We deliver to eligible addresses within the United States and to eligible international destinations shown at checkout.
If a destination, shipping service, or product is not eligible for delivery, checkout will not offer that shipping option.
2. Order Processing Time
Orders are generally processed within 1–5 business days before shipment. Processing time is separate from carrier transit time.
Our order cut-off time is 6:00 PM Pacific Time (PT). Orders placed after the cut-off time, on weekends, or on applicable holidays begin processing on the next business day.
Processing may include order verification and preparation for shipment.
3. U.S. Shipping Methods, Costs, and Transit Times
For eligible U.S. addresses, our current shipping options are:
- Priority Shipping: $5.99 — estimated carrier transit time of 1–2 business days after shipment.
- Standard Shipping: $2.99 — estimated carrier transit time of 3–6 business days after shipment.
- Free Shipping: $0 — estimated carrier transit time of 5–8 business days after shipment.
Total estimated delivery time includes both the 1–5 business day processing period and the applicable carrier transit time. The shipping service, cost, and delivery estimate available for your order are shown at checkout before payment.
4. International Shipping
We ship to eligible international destinations. Available international shipping services, shipping charges, and estimated delivery times vary by destination and are displayed at checkout.
For eligible international orders, applicable import duties and taxes are calculated and collected at checkout where required. When these charges apply, the order is shipped on a duties-and-taxes-paid basis so that the same import charges should not be collected again at delivery.
International delivery estimates may be affected by carrier operations, customs processing, local holidays, weather, or other events outside normal transit conditions.
5. Tracking
When tracking is available, you will receive shipment confirmation with tracking information after the order has shipped. Please allow up to 48 hours for tracking information to become active after the carrier receives the shipment.
6. Address Accuracy and Changes
Please review your shipping address carefully before submitting an order. If you notice an address error, contact us as soon as possible. We will try to help before shipment, but an address change cannot be guaranteed once fulfillment or carrier processing has begun.
Additional carrier or re-delivery charges resulting from an incorrect or incomplete address may be the customer's responsibility where permitted by law.
7. Delayed or Lost Shipments
If your shipment has not arrived within the estimated delivery timeframe, please contact us. We will review the tracking information, work with the carrier when necessary, and assist with an appropriate resolution based on the circumstances.
Delivery estimates are not guarantees and may be affected by carrier delays, weather, public holidays, customs processing, or other transportation disruptions.
8. Damaged, Defective, or Incorrect Deliveries
If an item arrives damaged, defective, or incorrect, contact us within 7 calendar days after confirmed delivery. Please include your order number and clear photos of the item, packaging, and shipping label when relevant.
Approved cases are handled under our Return & Refund Policy, including return-shipping assistance when the issue is our responsibility.

To qualify for a standard return, the item must generally be:
- Unused, unwashed, and in its original condition.
- Returned with the original packaging, tags, accessories, manuals, and other included components, when applicable.
- Not specifically identified as final sale or non-returnable before purchase.
Products that show use, alteration, avoidable damage, missing components, or other conditions outside the eligibility requirements may be ineligible for a refund.
3. Product-Specific Non-Returnable Items
Some products may be non-returnable for hygiene, safety, customization, final-sale, or other product-specific reasons. Any such restriction will be disclosed on the product page or before purchase when applicable.
4. No Direct Exchanges
We do not provide direct exchange service. If you want a different item, size, color, model, or version, return the eligible original item under this Policy and place a new order separately.
5. How to Start a Return
Returns are handled by mail. Before sending an item back, contact our customer support team through the Contact page or the current contact information displayed in the website footer. Please provide:
- Your order number.
- The item or items you want to return.
- The reason for the return.
Returns sent without required return authorization may be delayed or refused.
6. Prepaid Return Label and Return Shipping Cost
For eligible mail returns, a prepaid return label is included in the package.
For a standard return made for customer-choice reasons, the actual carrier postage charged for use of the prepaid return label will be deducted from the approved refund. We do not charge a separate restocking fee.
If the return is required because the item arrived damaged, defective, or incorrect and the claim is approved, we cover the return-label cost.
If you choose not to use the provided label when an alternative return method is authorized, use a trackable shipping service and keep your shipping receipt until the return is completed.
7. Original Shipping Charges
Original outbound shipping charges are non-refundable for standard customer-choice returns, except where required by law. If the return results from an approved damaged, defective, or incorrect item, applicable shipping charges will be handled as part of the resolution.
8. Refund Review and Processing
After the returned item is received, we inspect it and notify you whether the refund is approved.
If approved, the refund is issued to the original payment method. We generally process an approved refund within 1–3 business days. After the refund is issued, your bank or card provider may require an additional 5–10 business days to post the funds to your account.
9. Damaged, Defective, or Incorrect Items
If an item arrives damaged, defective, or incorrect, contact us within 7 calendar days after confirmed delivery. Include your order number and clear photos of the item, packaging, and shipping label when relevant.
