Troubleshooting

If you encounter issues during the installation process, don’t worry. Here are some common problems and solutions to help you troubleshoot:

Problem: The pet door doesn’t fit properly

If the pet door doesn’t fit properly, it may be due to incorrect measurements or an incorrect installation. Double-check your measurements and make sure the pet door is installed according to the manufacturer’s instructions. If the problem persists, contact the manufacturer for assistance.

Problem: The pet door panel won’t stay in place

If the pet door panel won’t stay in place, it may be due to a loose or damaged locking mechanism. Check the locking mechanism and make sure it’s securely fastened. If the problem persists, contact the manufacturer for assistance.

Problem: The pet door is letting in drafts or moisture

If the pet door is letting in drafts or moisture, it may be due to improper installation or weatherstripping.

Problem: Your pet won’t use the pet door

FAQ

Where is the best place to put a cat door?

If you aren’t simply installing it to give access to the yard, then one of the best places is a wall or window that leads to a nice alley. Alley-entrance doors give your cat a more concealed way in and out where they are less likely to run into surprise predators.

As they aren’t wide-open, your cat can easily peek through the door to ensure the alley is empty safe and then slink out for a day or night on the town!

How much does it cost to have a cat door installed?

A lot will depend on the type of door and where you are installing it, but you can expect an average installation rate to fall in a range of as little as $75 to as much as $300 – plus the price of your door. Typically, it will be in the lower end if your door is fairly standard or it’s a sheetrock wall install.

How big does a cat door need to be?

The easiest way to determine the perfect size will require measuring your kitty. Get a tape measure and measure your kitty’s hips. Add 1 to 2 inches to this measurement and you have the ideal door width.

Next, measure your kitty from the tips of their shoulder blades down to the belly. Add 1 to 2 inches to this and you have the perfect height. Pick a door that fits these dimensions or is larger and your cat can use it just fine.

Does a cat flap affect home insurance?

A cat flap is considered to be a security risk by many providers of insurance, so you should check before you install a cat door. Some providers may require additional security to maintain coverage or your premiums may have a slight increase.

Just be sure to check, as you don’t want to accidentally void any future claims.
