Thought maybe somehow I didn't get good contact but I have tried different cats mutliple times and they still have fleas a week later. I did notice the fleas seems less active (not as jumpy when removing) but they are definitely still present a week later and still laying eggs. Do not waste your money. Just go straight to revolution.

This is a very nice burrow for cats but it is very small and my cats are large. I followed suggestions in other reviews and cut the closed end out. My cats play with it and one cat grab the toy and ran to the house with the tunnel and toy. It was cracka because the other cat was chasing her. It's probably more designed for kittens. I have a large 7 lb cat very long and she hasn't gone in inside of it except for one. 10 lb already and she's a little bit leery about going inside also because it's so small. By cutting the closed and off they had more interest in it. If you have large cats I suggest not to buy this toy.

My cat was using this flea medicine for many months. Most recent application caused my cat to rip out all of his fur where the medication was applied. It cost us many vet visits to treat the reaction spot, and although he is better now, I have been too scared to apply flea medication again.

I have tried other brands with a similar application, some work a little, some make my cats sick for a day or two. After having tried flea shampoos, washing, spraying bedding, carpets, and furniture with insecticide, powdering cats and bedding with diatomaceous earth, I finally tried Advantage. Clearly the best for my particular cats. Fleas are gone and the cats are happy again.

This stuff actually works. I originally bought it at my vets office, but found it here for less. It also did NOT kill any of my babies like Only Naturals did. I've had to use it twice as the first time I tasted my house did not work. Hopefully this time it killed all those pesky fleas.

It didn't kill my cat but killed the fleas

I was terrified it would cause seizures in my old, frail, compromised girl who has CH and is prone to seizures but I had no choice the fleas were eating her alive

I was terrified it would cause seizures in my old, frail, compromised girl who has CH and is prone to seizures but I had no choice the fleas were eating her alive. So with much prayer I used it on Gina and the same for larger cats on the other two. It worked better than any other brands I have used in the past and no sude effects! I am very happy with the safety and performance of this product.

We recently took in a stray kitten. She had no signs of fleas at first but within a few days we found flea dirt. Immediately ordered this. It was here within 48 hours. In that time we were flea combing daily and found 2 fleas the next day. We didn't find a single one on any of our four cats after administering this.
