The Redmon Digital Pet Scale uses precision digital technology to clearly display your pet's weight in large, easy-to-read numbers. Easy and effective weight management in either pounds/ounces or kilograms. The tare function lets you accurately weigh pets in crates by subtracting the weight of anything other than your pet. When used in a single pet household, the memory feature shows you how much your pet has gained or lost since the last time your pet was weighed.
