>> best money I've spent this year (well nearly),
I totally agree Yorkie - its seems like a bit of an outlay at first, but its the only thing Ive found that does keep them clear.
A friend of mine never used it on her cats saying it was too expensive.. but then would spend a small fortune every other weeks with powders and sprays, which in the long run added up to more than I spend.
A tip yorkie - after youve been using it a while, you dont need to apply it every month and can start increasing the time span in between each application. Even my vet admitted that it doesnt need doing monthly once they're used to it and as long as theres no infestation.
I was a bit late doing the 2 month dosage and only recently remembered that it was 10 weeks since I'd last treated them.. yet even though its "flea season", none of them had fleas - and believe me they are very easy to spot on chaz so I'd know if he had them.
