Easy to install, cats can get in easily. I literally installed this using an Xacto knife and a cheap hand saw (obviously my door was cheaply made). The photo shows my tabby cat weighing 7 pounds and a black cat weighing 13 pounds. The larger of the two cats had to duck a bit to get through, I think the smaller of the two doors would have narrowed. We're hoping this reduces the smell of the toilet in the basement now that we can keep the doors to this room closed.
