The Beaphar Soft Cat Flea Collar contains an insecticide that kills fleas on your cat and prevents their return for up to four months. This comfortable fabric collar has been fitted with an elastic safety link. The safety link is designed to stretch if your cat gets caught while out and about, enabling them to slip their head out. The collar can also be adjusted to fit any cat. The Beaphar Soft Cat Flea Collar comes in a variety of colours, including red, blue and black, with a fabulous velvet finish and an optional silver bell. Suitable for cats and kittens from 12 weeks of age. 95% of the fleas life cycle is in the home. When tackling a flea problem, in addition to treating your pet, always use a household insecticide, such as Beaphar FLEAtec Household Flea Spray or Beaphar Household Flea Fogger for your home.
