The Seresto flea and tick collar provides up to 8 months of continuous protection for cats and kittens from 10 weeks of age. Covering both fleas and paralysis ticks, it's designed as a set-and-forget prevention measure — no monthly treatments, no application anxiety, just one collar replaced twice a year.

Active ingredients are released gradually from the collar material at low, sustained concentrations rather than as a single topical dose. The collar is odourless and water-resistant, remaining effective through rain and incidental exposure. Beyond killing adult fleas, it also targets flea larvae in the cat's immediate environment, disrupting the life cycle rather than just addressing visible infestation. An adjustable design fits most cat and kitten sizes.

For owners in paralysis tick regions — coastal and bush areas of Australia — having flea and paralysis tick coverage in a single product simplifies the prevention routine considerably. It's also a practical choice for cats that resist monthly spot-on applications or are difficult to handle for routine treatments.
