Fleas can really make your cat miserable, giving them restless nights, discomfort, and constant scratching. That’s why Cheristin for Cats is an effective, fact-acting, gentle flea treatment. It’s made specifically for kittens and adult cats. This topical flea treatment contains the active ingredient Spinetoram, which begins killing fleas within half an hour and helps remove over 98% within just 12 hours.
Cheristin works by affecting fleas’ nervous systems. This action stops fleas from biting and multiplying (reproducing). Each application protects your cat for up to 6 weeks. Though the veterinarian may recommend using it monthly to keep flea infestation from returning. Each single-dose tube lets you apply Cheristin right at the back of your cat’s neck without any fuss or mess, just quick relief.
Cheristin is non greasy, quick drying, and safe when used as directed by your veterinarian, which makes it a convenient option for households with more than one cat. It provides reliable and long lasting relief, further helping your cat stay comfortable, itch free, and protected from recurring flea problems.
Cheristin treats & prevents flea infestations in cats (including kittens) 8 weeks of age or older.
Firstly, you have to make sure that your cat meets the age and weight requirements (at least 8 weeks old and 1.8 pounds (lb) or more). Then follow these steps to apply Cheristin:
