Review : 4Kg, 7Kg 의 두마리 고양이를 반려하고 있습니다. 다묘가정이라 접종비도 만만찮은데 이렇게 저렴하고 편리하게 주문할수 있어서 좋았네요~ 저는 일주일정도 걸려 받았는데 빠르게 받은 듯 합니다. 매우 만족해요~

Review : I've been getting Stronghold here for over 3 years. I was paying triple at my vet's until I found this site. The delivery is quick, the product is A-1 and the costs--well, look for yourself. I have a BS in biology and do cat rescue and I haven't found any place that can beat Pet Bucket. I even turned my own vet onto this site! You won't be sorry.

As your cat is borderline you may like to continue to use what you have and monitor closely to see if it is effective. However we are not vets and would strongly recommend you seeks vets advice if you are unsure.
