How Often Should You Apply Advantage Multi for Cats?
Advantage Multi for Cats is a broad-spectrum, prescription treatment designed to protect your feline companions against multiple parasites. To ensure optimal efficacy, it is essential to apply this medication consistently and correctly. One of the most common questions pet owners ask is: how often should I apply Advantage Multi for my cat?
Recommended Application Frequency
Advantage Multi for Cats should be applied once every 30 days. It is a topical solution that acts systemically within your cat’s body to eradicate and prevent pest infestations. Continuous, monthly applications are advised for comprehensive coverage.
- Minimum dose: 4.5 mg/lb imidacloprid and 0.45 mg/lb moxidectin
 
- Apply topically every 30 days without skipping a dose
 
- If a dose is missed and more than 30 days have passed, apply immediately and resume the monthly schedule
 
Dosing Guidelines Based on Weight
Advantage Multi comes in pre-measured applicator tubes based on your cat’s weight:
- 2–5 lbs: 0.23 mL
 
- 5.1–9 lbs: 0.4 mL
 
- 9.1–18 lbs: 0.8 mL
 
- Over 18 lbs: Use a combination of tubes
 
Cats must be at least 9 weeks old and weigh a minimum of 2 lbs before receiving treatment.
Why Monthly Application is Necessary
The two active ingredients—
imidacloprid and 
moxidectin—target different types of parasites:
- Imidacloprid (10%): kills fleas on contact before they bite
 
- Moxidectin (1%): effective against heartworm larvae, roundworms, hookworms, and ear mites
 
These active ingredients degrade over time, and monthly reapplication ensures a steady level of protection. Clinical studies show that the drugs maintain effectiveness throughout the month, but skipping or delaying doses increases your cat’s vulnerability to infestation.
Application Instructions
To apply Advantage Multi correctly:
- Remove one dose tube and hold upright
 
- Break the seal using the reversed cap
 
- Part the hair at the base of the neck until skin is visible
 
- Apply the entire contents directly to the skin
 
- Do not massage in; lift tube before releasing pressure
 
Important: Apply at the base of the head to minimize the risk of the cat ingesting the product during grooming.
Post-Application Guidelines
To ensure safety and efficacy:
- Do not bathe your cat for at least 90 minutes after application
 
- Avoid letting pets groom each other for at least 30 minutes
 
- Prevent humans and other pets from touching the site for 30 minutes
 
- Always wash your hands after application
 
Common Side Effects
Though generally well tolerated, some cats may experience:
- Mild behavioral changes: agitation, hiding, excessive grooming
 
- Site reactions: redness, scabs, hair loss
 
- Gastrointestinal issues: vomiting, diarrhea, decreased appetite
 
- Neurological signs (rare): ataxia, tremors
 
If adverse effects occur, consult your veterinarian immediately.
Precautions
Avoid using Advantage Multi in:
- Cats under 9 weeks of age or under 2 lbs
 
- Sick, debilitated, or underweight animals
 
- Pregnant or lactating cats (safety not established)
 
Additional Benefits of Monthly Advantage Multi Use
Consistent monthly use not only maintains protection but also offers these benefits:
- Eliminates the need for pills—easy topical application
 
- Prevents multiple parasites: fleas, heartworms, roundworms, hookworms, ear mites
 
- Kills fleas before they bite—reducing skin irritation and allergic reactions
 
Storage and Handling
Store at room temperature (39°F–77°F) in original packaging. Keep away from children, pets, moisture, and open flames.
