Please Note: The Castor & Pollux Flea Collars have been discontinued. For similar products, please visit The Natural Research People.

Made with all-natural oils, these herbal collars smell great and help repel fleas and ticks.
Collars come in two sizes:

• Small: for puppies and cats, measures up to 12"
• Large: for dogs, measures up to 21"

The special process used to make Castor & Pollux Herbal Collars infuses the essential oils in the beads of plastic before the plastic is molded into the collar.  This results in the oils being spread throughout the collar for an even and safe application.  The release of these oils is slow and controlled.  We do not recommend direct application of oils to the skin or oral ingestion.

Ingredients:
Natural Oils of Pennyroyal, Eucalyptus, Cedarwood, Citronella, and Rue.

Directions:
Remove collar from package only when your pet is ready for a new collar. Carefully buckle the collar around your pet's neck, keeping one to two fingers under collar to prevent irritation from a collar that is too tight. Collar should fit easily over your pet's head. Cut excess collar, leaving two to three inches for adjustment. Collar is effective when wet, dry or dirty.

How long will the collar last?
It all depends on how much time your dog or cat spends outside, but the average collar should last about 3 months.
