The Seresto collar for cats is reasonably priced compared to similar products. On average, the Seresto collar that lasts about eight months costs about $60, sometimes less depending on the source. In comparison, an eight-month supply of Frontline Plus costs about $85 to $90. Frontline GOLD costs about $85 for only a six-month supply. Advantage II (which does not treat ticks) costs about $60.
So among similar products, it is not the most expensive, though other products generally have faster kills times for fleas and ticks. But the other products don’t provide repellency and they require monthly application. There are always advantages and disadvantages to making any flea/tick product decision. Make sure to discuss any questions you have with your veterinarian when trying to decide which product may be the best for your kitty.
