Pheromone Collars for Dogs and Cats, 4-Pack

Each pack holds four collars in a single solid color, made from TPR, a flexible rubbery material. There are two versions: a dog collar about 24.5 in (62 cm) long and 0.55 in (1.4 cm) wide, and a smaller cat collar about 15 in (38 cm) long and 0.4 in (1 cm) wide. Pick the dog or the cat version when you choose your option, since the lengths are different.

The strap has a notched design that lets you set the length with a simple clip-in closure, so you can fit it to your pet's neck rather than guessing from a size label. Colors are purple, gray, blue, black, pink and orange. All four collars in a pack are the same color, which makes it easy to keep a spare on hand or to share a pack between pets in the same home.

Measure your pet's neck before you order and compare it with the collar length, keeping enough room to slide two fingers under the collar once it is fastened. It is a plain strap with no tag ring or buckle, so it works alongside your pet's regular collar or ID tag rather than replacing them. Four collars weigh about 2.8 oz (80 g) in total.
