Frequently Asked Questions

  • Which Size Cat Door Do I Need?

    A cat will need to use a small or medium door. Measure your cat’s width and height. As shown on our measuring guide, the top of the door flap should be at least as high as the top of your cat’s shoulder. 


    One of these two sizes will fit:

    • Small Cats: 6″ in width by 11″ in height.
    • Medium Cats: 8″ in width by 15″ in height.

    Don’t hesitate to call us if you have any questions. Selecting the right size door will support your cat’s long-term comfort and well-being.

  • Do I Have Color Choices?

    We offer three desirable color options for our cat door window inserts:


    • White: a perfect match for many home windows.
    • Satin: a smooth silver, similar to the matte side of aluminum foil.
    • Bronze: a dark, rich brown hue.

    The inserts have a discreet frame design, allowing the maximum area for viewing. A security panel slides smartly over the opening whenever you prefer not to allow pets to go in or out.

    The short answer to this question is yes, cat door window inserts can be secure, and they can keep your cats safe. Cat door window inserts are designed to provide your cats with access to the outdoors while still maintaining the security of your home. 


    These inserts are typically made from a durable plastic or metal material and are designed to fit securely into the frame of your window. They come with a locking mechanism that prevents unauthorized entry and keeps pets from escaping. 


    Additionally, many cat door window inserts also feature an alarm system that will sound if someone tries to break in. With the right cat door window insert, you can easily protect your cats and keep them safe.


  • Are There Any Special Considerations When Choosing A Cat Door Window Insert?

    Yes, there are several factors to consider when choosing a cat door window insert. 


    Firstly, you need to make sure the insert is the right size for your window and your cat. You also need to consider the weatherproofing of the insert, as well as its security. Make sure the insert is made of durable materials and has an adequate locking system so that your cat can stay safe and secure. 


    You’ll also want to take into account any other features you may need, such as a dual-flap system or a timer for when you want to keep your cat inside for a period of time. 


    Finally, ensure that the insert is simple to install and maintain.
