Why Do Many Cats Prefer A Window-Access Cat Door? 

The new pet door for windows offers a game-changing solution for cats that are much more comfortable and accustomed to going out and in through a window. If given a choice, most cats prefer going in and out through a window or other access point well above ground level. But why?

Cats naturally feel more secure in higher places above the reach of unfamiliar animals. Whether there are any around or not, cats are instinctively wary of unexpectedly encountering potential ground-level dangers in their vicinity. There are multiple other natural reasons why cats enjoy being in higher locations.
