Slow Release Technology: This technology allows the collar to release the active ingredients gradually, ensuring that the protection lasts for several months. This continuous dispersal means that your cat is shielded from flea infestations over a prolonged period without needing frequent replacements.
Water Resistance: Water-resistant collars can withstand exposure to moisture from rain or baths, maintaining their efficacy. This is particularly important for cats that enjoy playing with water or may occasionally need a bath.
