Remove product tube from package. Holding tube with notched end pointing up and away from the face and body, cut off the narrow end at the notches. While holding the cat with one hand use the other to apply the solution. Invert the tube, and use the narrow end to part the cat's hair while gently squeezing to apply to the cat's skin. Hold the cat for a few seconds to give the solution time to be absorbed into the coat. When finished, wrap the tube in paper and put into the trash.

Sentry Natural Defense Flea & Tick Squeeze-On for Cats & Kittens is rated 3.4 out of 5 by 33.
Rated 4 out of 5 by from So far so good! I just purchased this for my two cats. The smell is really strong, but I actually find it very pleasant. It kind of smells like Chai Tea and Citronella. It does dissipate after a little while. I like it though. I feel comfortable putting it on my cats knowing it's all natural. I really worry about putting chemicals on them for flea and tick protection and this makes me feel like I'm still protecting them from fleas and ticks (they're indoor cats so they don't go outside, but it prevents them from getting anything the dog might bring in) and I know that the chemicals aren't harmful. I plan on continuing to use this product. Plus it's a great price on Chewy.com!

Rated 5 out of 5 by from Finally a Natural Flea/Tick Product I purchased the Sentry Natural Defense because my vet recommended it. When we adopted our cat from the shelter, this was the flea/tick product that our Vet applied to our cat. He had no bad reactions at all. Will apply shortly as soon as weather warms up a bit. Good product & again, much more natural for one's pet!

Rated 5 out of 5 by from Best Purchase I was wanting a natural flea and tick spot on for my cat. I hate the idea that every month I was putting something on my kitten that was not only poisonous to the fleas and ticks, but her as well. I found Sentry Natural for dogs at a local store, but no store in my town or the surrounding towns offered it for cats. I was very relieved to find that chewy sold it. It works great on my kitten, who is outside, no fleas or ticks on her and nothing poisonous!!!

Rated 4 out of 5 by from It works and it's natural! I have recently used both the cat and dog versions of this product, and love it! I was fostering a cat that an "on the market" product was used and she got very ill. I thought I might have to take her to emergency. But this product didn't cause any issues with her. She was her normal self after I applied Sentry Natural Defense and it works great! I did find that I needed to re-apply within, or at the 30 days, and as others say "it is strong smelling first day". But not anything that isn't worth the good results and healthier approach! I live in the country, and although my cats are indoors, my dogs go in and out of the yard! This year has been bad for fleas, ticks and flies! Glad I read reviews and tried this product!

Rated 1 out of 5 by from DOES. NOT. WORK. This product is not a money saver. If your experience is like mine, you will end up wasting a lot of time, energy, and more money on dealing with all the fleas that stick around and lay eggs that hatch after you apply this to your cats. I think it kills some adult fleas at first, but it's just not effective enough to end even a low-level infestation. Also, the fluid itself is excessive in volume. No matter how well you place it on a cat, it SPREADS down the fur and the cat will be able to reach it with her tongue, ending up miserable. I have 3 indoor-only cats who still have fleas after using this product 2 weeks ago. I'm faced with the prospect of giving them thorough baths so that I can put on chemicals. Thanks, Sentry!

Rated 1 out of 5 by from Not strong enough I used this on all three of my cats (one inside only, two indoor/outdoor). There was a lot more liquid in comparison to the regular chem. treatments. I didn't see any of them scratching, but I got fleas inside my home (which I never did with the regular chemical spot treatments). It also makes them smell like old hippies (cloves and peppermint).
