I was very wary of using this on my cat because of the negative reviews and illness/death associated with this product. We have used this on our 2.5 year old cat twice now and it is the only treatment that has been effective- no other flea powders/tablets could treat her bad case of fleas. No adverse reaction after first use. This time she seems a bit quieter but still eating and drinking as usual. We were very careful with the placement on the back of her neck to make sure she couldn’t reach and lick the area and kept her inside for a few hours after use to monitor her. Would definitely recommend this product but we will only do the treatment on a day that we can stay at home and watch her.

My cat had ear mite big time. He was scratching, twitching his ears and sneezing. I have him a dose of advocate before taking him to the vet just to give it a try. Lo and behold, within minutes the symptoms began to desist and an hour later he was back to normal.
He showed no signs of nausea as some others have reported.

We had no luck with other products, so we tried Advocate after hearing good reviews. Our cats stopped scratching within 20 minutes, I'd definitely recommend this. Look after your pets well!

After applying to my cat, she has become very lethargic, whatever she eats she vomits, she seems unsettled... If I know I would never, ever put it near my cat. I cannot see how anyone can consider it something safe to put on cats. I am so angry I did not check the reviews before as I probably would not agree for it.

Observe your animals CAREFULLY when using this product. Both our cats start squinting and blinking their eyes the second it is opened. This was even on the first time we tried it. We have used it for several months as we thought it would be great as it was both for fleas and worms so the boys[ cats] didn't have to be treated with multiple things. But no more. I can smell it as well and it is horrid and almost burns your eyes so they water [yes, I am very sensitive to things as is our 12yr old son...if WE can then it's worse for the animals!]. One cat we have realised vomits in the first 24hrs it is administered. The other has diarrhea for a week every time. Never had any of this with other products.

I have treated both of my adult cats today with advocate and they have both had a bad reaction to it. They appear scared and jumpy, if I go near them they cower as if I’m going to hurt them and are behaving weirdly in general. I do hope this reaction wears off soon, it’s been quite scary to watch them . I certainly won’t use this again !!

It is a great prevention treatment for all paracites including heartworm and it also keeps your cats free of fleas!

I have used this for many years and have been happy with it. I recently used it again on my 16 year old cat and within 24 hours she stopped eating, retreated from contact with us and was generally unwell for about 10 days. Unfortunately I can't use this again.

I’ve used this on my cat twice now. The first time she started acting out of character. Usually very friendly and loving affectionate cat she became distant and wasn’t eating her food. Only lasted a few days didn’t think too much of it. Gave her another dose yesterday and she’s been so distant all day, getting very angry, not coming inside like she usually does at night and angry everytime I approach her. I’m convinced it’s because of advocate. Won’t be giving it to her again.

Vet administered in the surgery, but put on too low below shoulder blades. Cat was able to lick. Within 24 hours, cat was wobbly, nearly falling over, twitching and trembling, distressed, dilated pupils. He survived thank goodness but this product is lethal and there is no antidote. SHOULD BE BANNED

What are we putting into our pets,? I used my normal advocate from the vet on my cat,he then curled up and fell asleep with the area I put the advocate against the skirting board,when he woke up the paint on the skirting had blistered and peeled off (what are we using on them)

After applying this product on our beloved cat, she has not been able to eat or drink for 2 days, getting excited at the thought of eating and yet unable to eat, horrible!
Bayer should reconsider selling this product as it is! It has definitely more bad side effects than good ones!!!

My cat nearly died after this was applied to him, vomiting, constipated, cramping. Very unwell. These companies have a lot to answer too.

Two of my four cats have had a bad reaction in this product, first time use an will never use again. Staggers, dilated pupils, an tremors. They probably have licked some of, but ha cats are pretty good at doing that and I've never seen a reaction like this. My poor kitty's.

I brought this on Friday and applied it to my cats and I noticed the next day that my cats had a scab and thier hair has fallen out not happy about this as I paid $90.20 for it and it has hurt my cats
