FELIWAY (Ceva)FELIWAY Optimum Diffuser Starter Kit

FELIWAY Optimum is the gift for a household with a stressed, nervous or newly-adopted cat — or ongoing tension between two cats. The plug-in diffuser releases what the manufacturer calls its most advanced feline pheromone complex, which it says helps reduce common signs of stress such as spraying, scratching and hiding, and eases multi-cat conflict; it is drug-free and widely stocked. One refill covers roughly 70m² for about 30 days, and the starter kit sits around £26. It ranks here rather than higher for two reasons: the ongoing refill cost adds up over a year, and — as with any pheromone product — results vary between cats and some owners report little change. Still, as a considered, problem-solving gift it stands apart from the toys and treats above it.
