Pet Flea/Tick Pendants

I wish these would have worked from our cats but they are too big. It's the same size for dogs, so if you have dogs or big cats, they should work. The company didn't issue me a refund, so I'm trying to make up the loss. One outer package is open(inner is sealed), and everything is new! $18 each/$60 for 4 Below is their description/correspondence regarding the pendants: The pendant is 2.48 x 1.18 x 0.59 inches in size and weighs 0.52oz. It's the same for both cat and dog. Our flea and tick pendant is designed to be effective for all sizes of dogs and cats, as well as puppies and kittens at 8 weeks old. Our pendant is very stretchy and can fit collars to any size. The dosage of the natural ingredients is the same for all sizes of dogs and cats, so you can be sure that your furry friend is getting the same level of protection. The design of our FurLife™ pendant ensures that the release of natural essential oils is controlled and consistent, tailored to create an effective shield, even suitable and safe for smaller pets. This is thanks to our SmartRelease technology, which adapts to your pet's environment rather than their size, ensuring safety for all.
