CatHole Cat Door

It all started in 2004. We, like many cat owners, wanted to put our cat's litter box in the basement. But, we didn't want to leave the basement door open. So we made a cat door by cutting a small arch-shaped hole in the closed door. This worked fine, but we didn't like the appearance, and Motchka's loose hair was constantly collecting on the edge of the hole.

We made a pair of arch-shaped wood frames to cover the hole and painted them. We then looked for a way to fill the void between the frames and decided that a grooming brush would be the ideal choice. It would collect loose cat hair efficiently and would help keep our house cleaner.

We decided 'CATHOLE' would be a good name for our cat door because the attractive arch resembled a large mouse hole. The name became the butt (excuse the pun) of many jokes by our friends. Regardless, we liked the name and have had it trademarked.

CATHOLE became a conversation piece. 'Why don't you patent it?' We did - but that was only the beginning of a long voyage. Even though our sales are doing quite well, we are still a 'mom and pop' company. Our company has become a major effort for us - after we retired.

CatHole FAQs

How do I install the Cathole?

This is a fairly simple DIY project, though it does require some tools. Using a jigsaw, cut a hole the size of the product dimensions into your soft or hollow core door. Attach the cat door, and done! Easy installation!

Can I use this as my cat flap door?

Because the Cathole is a literal hole in your door, we would not recommend installing this into an exterior door. If you want an interior pet door that leads to indoor living spaces such as the laundry room or a spare room that has the messy litter box in it, the Cathole is right for you. If you want a traditional dog door, we recommend that you checkout our full list of cat doors, which features pet doors from Ideal Pet Products, Petsafe, and more.

What is the Cathole made out of?

The wood arch is made out of baltic birch, which can be stained to match the aesthetic of your door.

What are some uses for my Cathole?

You can install the Cathole into any inside door that you want to keep closed while giving your cat access. For example, you can install it into a spare closet door that has your cat food, cat tree or scratcher, or even your cat box on the other side.
