Questions, fetched.
Does it work on cats?
We tried. The cats declined to participate and knocked the prototype off a table.
How long does the battery last?
About 14 days per charge. The dock is shaped like a small bone, so nobody forgets where it is.
Is it waterproof?
Rain, puddles, the sea, and that one pond you told them not to go in. All fine.
What size dogs does it fit?
Chihuahua to Great Dane. The tag weighs less than a large treat.
Give your dog a reason to be smug.
