Hartz Nature's Shield Flea & Tick Spray

I was very happy to receive this free can of Nature's Shield Natural Flea & Tick Cat Spray! I'm all about using products that contain safe ingredients and this has been so great! My inside cat wears the Hartz UltrGuard ProMax Flea and Tick collar, (which works amazingly). However, there are a couple of stray cats that like to stay on my front porch. I've been using the Nature's Shield to spray on my porch (especially the rugs) and it has been helping so much with keeping fleas and ticks off. It even helps with some ants that have been coming up trying to get to the cat food! This spray has been a blessing and I love that it's not toxic. It's free of parabens, dyes, and harsh chemicals. I sprayed some on the stray cats and they have not been scratching as much. I have also been using this on my indoor rugs at the doorway to keep fleas and ticks from coming inside and it works great. I also like the scent. It smells like cedar and lemons, which I love! I would definitely recommend this Flea and Tick spray!

Smells good

Kills fleas, ticks, and flea eggs by contact and also repels mosquitoes with natural oils. My cats seemed to itch much less after it was applied. They were initially afraid of the spray sound so I added a lick mat for them to eat while applying the spray. Botanical flea & tick protection with effective plant-based ingredients - cedarwood & lemongrass - with NO parabens, dyes, or alcohols Cleans, deodorizes and nourishes your cat’s skin and coat with Vitamin E and glycerin Safe to use around children, adults, other pets. I received this product for free in exchange for my review.

I received this item in the mail to try and let me tell you how awesome it is!!!!! I was having probs with fleas and ticks due to us having 3 cats and 5 dogs, and they were running us out of house and home UNTIL I sprayed Hartz Nature's Shield on my cats and my furniture; I even used it on the dogs and it works on them too! we said bye bye to fleas and ticks the day I sprayed!

Effective flea treatment

I received a free sample of Hartz's Nature's Shield Flea and Tick Spray in exchange for my honest review. This came at a perfect time because my three cats had fleas and there were also fleas in the carpet. At first it was hard to use because my cats didn't like being sprayed and kept running away so probably not the best product design. But I was able to get around it by spraying a towel and then wiping them down. I also sprayed some on the carpet for good measure. I think it was pretty effective since there weren't any signs of fleas after a few days. I also like the fact that it is plant based ingredients so it's safe for other pets and people. I would definitely buy again when I run out

Protective and Proactive

I am very impressed with this spray, as it is very easy to use and gives me peace of mind that I am doing what I can to safely protect my cats from pests like fleas, ticks, and mosquitoes. The canister is a large size and will probably last me a few years, as my plan is to spray it on every 2 to 4 weeks as a protective shield for my cats, who mainly live indoors but will venture into my fenced backyard to romp with their canine siblings. I used to use topical flea applicators, and my cats were a bit squirmy; this spray makes it so easy to apply since I don’t need to have my cats sit perfectly still! I love that the ingredients are plant-based and free of parabens and dyes, and the lemongrass oil adds a pleasant scent. My cats’ fur truly does look fluffier and shinier and feels softer thanks to the added vitamin E. The one possible downside is that it IS a large container, so I would be wary that it would lose potency before I finish it, but it is a great value. This is an overall wonderful and innovative product that all cat owners should keep in their home to give the best protection! I received a free product in exchange for my honest review. Opinions expressed within are 100% my own.

Hartz Nature's Shield Review.

Having cats sometimes means also having parasites especially if they go outside and this product is great for that. It's made with plant based ingredients and has an amazing smell that is pleasant and light. Spray evenly on my pets, the can has a lock system on the lid to prevent accidental spraying. My cats didn't seem to mind it and seemed to tolerate it well. it's best to do a test before using all over. It kills and repels several different types of parasites.

Good Natural Product

I recently Hartz Natural Shield Flea & Tick Cat Spray to review. It is a good natural product. It has quality ingredients. I feel confident to put this on my cats. It worked well. But my cats were scared of the aerosol can. I feel it would work better in a pump spray bottle.

Effective and convenient

Hartz Nature's Shield Flea and Tick cat spray is really works excellently I used this product, and I was surprised at how well it works, smelled, and that my cats didn't run away! I also used it on their sleep beds and normally, with other products I've used, they'd wait a day or two before using their beds. But, thankfully, they were in their beds that same day. It's good. You should try it!

I received this product for free in exchange for my honest opinion. This has to be the best and easiest flea and tick killer for cats. its all plant based and safe. You just spray your cat and it works quickly. My cat is super scared of the spray noise so I just sprayed it in my hands and then rubbed on his fur (which he loved). Seems to be working so far. Highly recommend to others.
