Apply the Correct Dosage
Advantage II flea drops are specifically formulated and tested for cats of certain weights. The full dose of the correct product needs to be administered on a monthly basis. The product can fail if the manufacturer’s instructions aren’t followed. It’s not uncommon for owners to under-dose their pets as a result of splitting treatments between animals. Toxicity concerns can also result in under-dosing.
Re-dosing Early
Do not apply more than one tube per treatment. Under normal conditions, one dose will last a month. However, in severe infestations, it may be necessary to retreat the cat earlier in order to establish control. For kittens (2-5 lbs.), retreatment shouldn’t be done more often than once every 14 days. For small cats (5-9 lbs.) and large cats (over 9 lbs.), do not retreat more than once every 7 days. Once flea control is attained, the monthly re-treatment schedule should be adhered to.
