Yes, cat flea collars are typically waterproof. Flea collars for cats are an effective way to reduce the flea and tick populations on your cat’s coat. The collar contains an insecticide and when it’s on, it kills off any fleas or ticks your kitty may have come in contact with.
Most cat flea collars provide a water-resistant coating, allowing your cat to go swimming or out in the rain without worry of weakening the collar’s effectiveness. Even when going through monthly baths and water treatments, these collars retain their efficacy. Just make sure you read the instructions carefully so you know how long you can leave it on before needing to replace it.
Final point
Whether your cat’s flea collar is waterproof will depend on its material composition. If you need a more durable option for water exposure, silicone or PVC plastic can provide better resistance. In addition, taking steps to keep the flea collar dry will help extend its life and performance.
