Door Buddy Adjustable Door Strap & Latch. Easy Way to Dog Proof Litter Box. No More Pet Gates Or Cat Doors. Convenient Cat & Adult Entry. No Tools Installation. Stop Dog Eating Cat Poop Today! (Grey) DOOR BUDDY ---&gt; This simple Door Latch that will keep your dog (if slightly larger than cat) out of the room with the cat food and litter box while still allowing your cat to have easy access. SIMPLER ALTERNATIVE ---&gt; Door Buddy may be simple, but it works! Why struggle with pet gates that are bulky and cumbersome to use? Why cut a permanent hole in your door to install an interior cat door? Why force your cat to jump into and use a top entry litter box that may make her feel trapped? Try Door Buddy first and see for yourself why our customers LOVE it so much! INSTALLS IN SECONDS AND IS EASY TO USE ---&gt; Just peel and stick to the door and door frame using the strong 3M adhesive (2 EXTRAS included). The simple lock and unlock latch allows you to use it from either side of the door giving you quick and convenient access to the room. ADJUSTABLE AND CUSTOMIZABLE ---&gt; Use the adjuster on the strap to make the width of the door opening wider or narrower to work with the exact sizes of your cat and dog. You can even alter the position where you stick the plastic pieces to make it further customizable. Or, install on the back of the door to make it stronger, especially for larger and more persistent dogs. Compatible with all types of doors from bi-fold doors to pocket doors and even double doors! HOW DOES IT WORK ---&gt; Door Buddy allows the door to any interior room to open just wide enough so cats can easily enter or exit, but at the same time keep it narrow enough so dogs (if slightly larger than cat) cannot get in. Sometimes keeping the peace in a household with both cats and dogs can be frustrating and a challenge. Door Buddy provides an easier and less cumbersome way to give cats a space of their own.
