Pros: Effective method of flea & tick control. Readily available and relatively easy to apply.
Cons: Cats didn't like it and tried to remove it themselves. Cats become ill.
The Introduction (Skip below if you're in a hurry).
When I noticed all three of my pets scratching and itching more often I declared war on an infestation of unseen fleas, ticks, or whatever else was aggravating my pets. My dog got the ol' flee bath which significantly helped. Since my cats would not go anywhere near the bathwater, I opted instead to use a topical treatment instead. Based on an extensive amount of research I did at Petco (meaning I chose the least expensive product on the shelf) I purchased a three pack of the Sentry Purrscriptions Plus Squeeze on Flea & Tick Control and applied a dose to each of my two cats.
Two weeks later, I've noticed a significant decrease in the scratching, itching, and irritability that my cats were experiencing, but I did have some minor concerns in the first few days after using the product. So here's my review...
Availability & Price
Sentry's Flea & Tick Control is readily available at most pet stores such as Petsmart and PetCo as well as certain drug stores and mega-marts. An online search of the product name came back with numerous websites that sold the product directly.
Sentry makes this product available in two concentrations based on the size of the cat. (Under 5 pounds and over 5 pounds).
I paid $10.99 for a package of three squeeze on applicators. If you have only one cat to inoculate this is enough for three months worth of protection. Because I had two cats and was looking for more of an immediate solution rather than ongoing protection, I now have an extra applicator. So I guess one of my cats will be protected for an extra month.
Directions seemed simple enough - cut open package, apply to the back of the cat's neck, allow to set it. This proved a bit more difficult that I expected. While my cat was calmly sitting next to me I attempted to open the applicator but wasn't able to. I had to get up (disturbing my cat) to find a pair of scissors then wait for my cat to come back while holding an open applicator and trying not to spill it all over m couch. Finally when my cat returned I dumped it on her neck and watched as she immediately jumped away and ran. The same process was basically repeated with my second cat.
Active Ingredients and Safety Around Children
Sentry's Squeeze on Flea & Tick Control has two main ingredients - Pyriproxyfen and Etofenprox. After I experienced a few minor problems with my cat (see below) I did a little research on them. Fortunately, and good for this epinion, both chemicals are relatively benign and harmless.
Etofenprox is the active ingredient used to kill live ticks and fleas. It is a chemical compound made mostly of water and carbon. According to most websites about it, etofenprox is a safe chemical to use around pets as well as children. It specifically targets only the class of bugs that fleas and ticks fall into.
Pyriproxyfen specifically targets eggs laid by fleas and ticks, it does not effect live insects. It has few side effects and no interactions with other medicines. Again, a relatively safe chemical to use around pets and children.
Problems I Experiences
Within 24 hours of using this product I noticed two problems directly related to using this product in both of my cats.
Immediately after applying to my cats, they both ran off and hid. When I found then I saw them both arching their necks trying to lick off the medication that was applied to their upper backs. Fantastic, I though, as I reread the warnings on the box clearly stating to avoid getting the product in the cat's eyes and mouth.
The next morning I discovered the second problem when I woke up to numerous "surprises" around the house. Both my cats had apparently become violently ill over the night and had vomited numerous times throughout the house. I obviously have no idea if this was a result of the cat's licking it off their backs or a side effect of the medication itself.
Fortunately neither problem seemed to last much longer than 24 hours and other than going through a roll of paper towels cleaning my house, the vomiting led to no other significant problems. A few days later I noticed that my cats did in fact appear to be more comfortable with themselves and all three of my pets - dog and cats included - appeared to have fewer fleas based on a significant decrease in itching and scratching.
Bottom Line & Recommendation
While the two ingredients seemed to be an effective and immediate method of flea and tick control, I think that in the future I will switch to a different method of application. Effective as it may be, I'd rather not go through another cleaning episode like I did a few weeks ago.
