Does Advantage II lose effectiveness over time?

I've been using Advantage II on my cat for flea prevention, but lately, it seems like she's been scratching more than usual and I've noticed a few fleas around. I've been careful to apply it monthly, just like always. Could the medication be losing its effectiveness over time, or might there be another issue at play?

Answer

It’s understandable to feel concerned when your usual flea treatment seems less effective, especially if your cat is scratching more and you’ve noticed fleas.

  • Reapply Advantage II correctly and consistently
  • Check for environmental factors contributing to fleas
  • Consider other underlying health issues

There could be several reasons why you're noticing more fleas on your cat. It's possible that environmental factors are contributing to a higher flea population, or that fleas in your area have developed some resistance. Another possibility is an incorrect application or bathing your cat too soon after application, which could reduce efficacy. Additionally, consider other underlying health issues that might cause increased scratching.

Frequently Asked Questions

  • How can I ensure the flea treatment is applied correctly?

    Make sure to part your cat's fur so the product reaches the skin, and avoid bathing your cat for at least 48 hours after application.

  • Could environmental factors be affecting the flea medication's effectiveness?

    Yes, a high flea presence in your environment can overwhelm the treatment. Consider treating your home and yard as well.

  • Could my cat be having a reaction to the flea medication?

    It's possible, although rare. Monitor for any other signs of a reaction like redness or hair loss, and consult a vet if you suspect an allergic reaction.
