We live in the city, so we like to keep the cat from running out the front door. There aren't a whole lot of options for creating indoor boundaries for cats. As one of the few, this one is alright.
The signal is not very consistent-- you're supposed to be able to create a radius of where you don't want the cat to be (in relation to the disk). The signal seems to be intermittent even when the collar has a brand new battery, so sometimes the cat can sneak all of the way up to the disk without getting zapped/warned.
Nevertheless, the cat has learned to be wary of the disk and now generally gives the front door a wide berth.Get more detail about PetSafe Indoor Radio Fence.
