Once you decide your cat needs a way through the sliding glass door, you face one real choice: a removable insert panel that sits in the track, or a replacement glass panel with the flap cut into it. Both work. They suit different people.
Here is an honest comparison so you can pick the right one for your home and your tenancy situation. Either way, both fall under cat door for sliding glass door installations we do across Dubai.

The track insert panel
- Best for renters. Nothing is drilled, cut, or glued. The panel lifts out when you move.
- Fast and simple. Measure, cut, drop in, seal. Done in one short visit.
- Slightly narrows the opening. The panel takes up a few centimetres of track width, so your door opens a touch less wide.
The replacement glass panel
- Best for owners. If you own the villa or apartment, replacing one glass panel with a pre-cut one gives the cleanest look.
- Full door travel. Nothing sits in the track, so the door slides open as wide as before.
- Permanent change. The original panel is kept aside or replaced, so this is not the renter option.
How to decide
Ask yourself one question: do you need to hand the door back unchanged? If the answer is yes, the insert panel wins without a contest. If you own the place and want the neatest finish, the replacement panel is the one.
Renters should also check the tenancy angle before choosing: do you need landlord approval for a cat flap in a sliding door? The short answer may surprise you.
