Cats groom themselves constantly, which spreads a flea problem across the whole coat faster than it would on a dog, and makes catching an infestation early more useful than with most pets. Monthly, ongoing protection tends to beat reacting once fleas are already visible.

FIPROtec Combo Spot on Cat is a veterinary-strength medicine combining fipronil, which kills fleas, with (S)-methoprene, which stops flea eggs hatching and multiplying in the home. Beaphar say it also kills ticks and biting lice, and that it can be used during pregnancy. It's suitable for cats from 8 weeks of age weighing more than 1kg, and the pack contains 6 treatments - six months of monthly cover.

Before you use it. This is a licensed veterinary medicine with a specific age and weight cut-off - 8 weeks and over 1kg - so weigh a young or small cat before applying rather than judging by eye, and read the leaflet in the box for the exact application method.

Who it's for: owners of a cat over 8 weeks and over 1kg wanting monthly, ongoing flea, tick and lice cover, including through a pregnancy.
