Customer feedback praises ease of application and includes reports of no skin irritation, but experiences with flea reduction and treatment duration are mixed. Some customers report little flea control or effects lasting about 10 days, while others raise concerns about fur loss near the neck. Odor impressions also vary. These reports matter because the listing claims control for up to four weeks, but the aggregate ratings alone cannot establish how well an individual cat will respond.

Customers describe the treatment as easy to apply.

Negative themes

Some customers report that the treatment does not control fleas or lasts only about 10 days.
Some customers report fur loss around the neck.
