WILL MAKE YOUR CAT SICK!! TOXIC PRODUCT
Disregard any positive reviews. My cat became extremely sick just a couple of hours after application. This product is highly toxic and should not be used on pets, let alone sold on shelves at major retailers like Target. I have previously used PetArmor and Advantage on my cat without any issues, so this reaction was especially alarming. Within about three hours, my cat began acting very abnormal. He was drooling and foaming at the mouth, twitching, shaking, and extremely sensitive to any movement or sound. It was terrifying to watch because he was clearly not himself. His pupils were dilated, and his behavior was erratic and distressed. I immediately bathed him using Dawn dish soap and washed the application area twice, but the chemical smell was still incredibly strong, which is very concerning. After doing further research, I found that this brand, along with Hartz, has been associated with severe adverse reactions in pets, including long term neurological damage, loss of motor control, and even death. This is not a safe product. Do not purchase it. I strongly urge all pet owners to avoid this brand and Hartz and to warn others as well.

Please do not purchase this
Do not buy this. My cat is usually great with topical flea meds. This one made her desperately itchy in the spot where we applied, the skin was red, her hair started falling off and the liquid did not dry but remained greasy and made her hair clumped for so long. We had to just wash it off with a cloth and hope she would be okay. She was also just acting weird. Gave us such a scare. If you look this up, so many people experienced the same. This product NEEDS to be discontinued. The instructions didn’t even clarify where the liquid should be applied! That’s super dangerous for people that don’t know to put it on the upper neck where the cat can’t lick it. This is seriously concerning.

WHY IS THIS STILL BEING SOLD???
Target - at what point do you remove this from your shelves???? Purchased in store and did not read reviews prior. Horrible product that makes cats deathly ill. Will stick to the more expensive, well known brand.

I SHOULD HAVE READ REVIEWS FIRST! This ABSOLUTE GARBAGE product hurt my cats, it’s irritated them both so much and they can’t stop itching where it was applied. One of my cats still won’t let me near him, he hasn’t forgiven me. This stuff is poison!

I would leave zero stars if I could. I wish I read the reviews before purchasing but it was an in store purchase. DO NOT BUY! Way too harsh for my cat, he reacted to it instantly with constant scratching and (trying) to lick. He does not have fleas. It's just precautionary as he is an indoor cat so loves to lay by the front door. He ended up losing his hair at the point of application so he has a little bald spot now.

Skin sensetive product, hard to wash out
My cat had rush on her back because of this product. After few minutes she started to scratch herself and hair was falling off. Nedded to bath her 3 times after because it didn’t help after first or second time. Very stressful for cat and for me.

Sergeant's Guardian Pro Flea & Tick Topical.
Returned due to too many conflicting consumer reviews. Not clear if it would be a safe topical for my 'senior' cat.

Messy and smelly but mostly messy - doesn't absorb at all
This product leaves a huge greasy oily spot all over the back of the cat's neck. I've used these types of flea treatments before (just not this brand). I notice a lot of liquid seemed to be in the tube as I applied it and it wasn't drying or absorbing. I applied it to three of my cats. The liquid spread all over the back of my cats neck and the backs of my cats necks are the next day is still oily and greasy looking and to the touch. I even tried to wipe them with a pet wipe. It also has a very strong smell. I feel sorry for my cats and I can't wait for this stuff to wear off their fur. I'm also worried that the oil will spread to whatever they are laying on or that they will lick the area since it has spread to a spot that they can reach.

AWFUL!!!
Really wish I read the reviews before buying. Put it on my cat and she immediately went crazy. Super itchy and hissing and pawing at the site trying to get it off. I bathed her immediately, but she was still itching non-stop for 3 hours. Finally gave her some gabapentin to sleep, and she was ok. Terrible product, don’t let anyone buy it!

Never Again!
Gave my cat a terrible rash. When I woke up I found fur everywhere and a bloody bald spot where the treatment was applied and where he scratched all night from reaction. I feel horrible. My poor kitty. Never again!

Dangerous - DO NOT give to your cat~!!
I beg Target to please take this product off the shelves. It is extremely hazardous for cats' health. After giving it to my cat last night, I woke up this morning to find her foaming at the mouth, crying, shaking, blinking in confusion, and refusing to eat. I had to take her to the vet, where they tried to help flush the poison from her system. Please, Target, stop selling this. I bought it in the store but would never have touched it had I seen these other reviews.

Left a bald spot on my cat's neck after one treatment due to her being in extreme discomfort from the applied area. This is not something I would recommend to any cat owner, as she was in a lot of pain. We had to wipe the area clean and apply cat-safe creams to help sooth the area. The flea collars are a much safe option and have not harmed my cat at all.
