SENTRY Calming Collar for Cats and Kittens, One 30-Day Release Collar
Couldn't load pickup availability
This SENTRY listing contains one collar with an advertised 30-day release period. It is intended as a calming-collar product, so its fit, age guidance and replacement instructions matter more than matching it to a walking outfit.
Before you choose
Treat 30 days as the manufacturer's replacement schedule, not a guarantee of a behavioral result. Check the label for cats and kittens of the appropriate age, and do not use it as a leash attachment unless specifically permitted.

Questions about this product
How long is this SENTRY collar designed to release pheromone?
The advertised release period is up to 30 days for one collar. That period describes the product's release schedule, not a guarantee that every cat will show a behavioral change.
Is this a multipack?
No. This listing is for one SENTRY calming collar. Follow the package's fit and replacement instructions for that collar.
What storage temperature does the package specify?
The listed storage range is 59 to 86 degrees Fahrenheit, or 15 to 30 degrees Celsius. Keep the package so you can follow the full storage and use instructions.
Is this a liquid refill for a diffuser?
No. It is a wearable collar with a stated release period. It cannot be treated as a refill for a plug-in diffuser or spray bottle.
