A cat that grooms itself constantly will lick off almost anything applied to its coat, which is one reason a collar, worn rather than applied, suits a cat's habits better than some topical products.

This is a plastic flea and tick collar for cats and kittens from 12 weeks of age, worn continuously to repel both parasites, and Bob Martin describe it as intended for everyday, at-home use.

• Plastic flea and tick collar
• For cats and kittens from 12 weeks of age
• Worn continuously to repel fleas and ticks
• For everyday, at-home use, per Bob Martin
• Single collar (SGL)

One thing worth knowing. Bob Martin's own guidance is that a heavy, already-established flea infestation needs treating separately first — this collar is for repelling and ongoing prevention rather than clearing an existing heavy infestation. No collar length or neck-size guidance is given on this card.

Who it's for: owners of a cat or kitten from 12 weeks old wanting ongoing, passive flea and tick protection that doesn't rely on a topical application a cat might groom off.
