## Questions & Answers

**Q: Will this work on hollow core doors ? My door is a six panel door like the one in the picture but it is not solid wood.**
A: Yes, just do not use their template, insert the flexible straight piece into either side piece and trace on the outside of it for a perfect fit.  If you use their poor template it will be to big and not secure on a hollow core door.  I use Dremel rotary tool to cut the hole.  I think I used wood glue and clamps to attach it.  I would also glue the flexible straight piece onto one of the side panels or it will slide around.

**Q: What are the dimensions of the kitty pass? Im looking for something that will fit on a slated door without disrupting the slats.**
A: The hole itself is roughly 7".  Cats have to lower themselves slightly but it also makes them feel hidden once inside.  It does NOT paint well.  It took several tries.  See other post for the additional dimensions.

**Q: Would use on door to the garage, what about the A/C or heat escaping?  Possible to attach a flap or door?**
A: This is designed for interior use.  It will leave an opening.  I would suggest a traditional pet door with a flap/insulation for what you want.

**Q: Is it wood or some other material?**
A: Thank you for your inquiry. It is made out of 1/2 inch PVC composite material

## Customer Reviews

### ⭐⭐⭐⭐⭐ Cute kitty door and easy to install.
*by G***G on July 20, 2025*

The media could not be loaded. I ordered the 9x12 cat door and I’m so glad I did. I was worried my cat would be too big but it’s perfect. I would say most cats I’ve seen would most likely fit through that size. It helps keep the litter box safe from my toddler and the cat food safe from the dogs! Installation is easy enough if you have a jig saw. I put painters tape under my cut line because I was worried it might splinter the wood. Even if it did, the frame of the cat door would cover up any imperfections.

### ⭐⭐⭐⭐⭐ Works great!
*by K***P on August 11, 2025*

It is perfect! Super cute and the two kittens loved it. I can close the door now where their kitty litters are and they can go in and out. We took the door off the hinges to cut it. Was straight forward. Keeps the smell contained now.

### ⭐⭐⭐⭐⭐ Easy to install and super cute!
*by A***N on August 2, 2025*

Perfect little pass-through for my cats to access the litter box in the bathroom of our RV. It is a lightweight, plastic material with easy instructions for installation
