The best gate with a cat door depends on your opening width, pet sizes, and whether you need extra height. The Babelio 36-inch gate is best for buyers prioritizing added height and adjustable cat-door positions. The Babelio Extra Wide is better for broader openings, while the Carlson suits openings within its specific width ranges. Two other options advertise auto-close features, but their provided product details are limited, so verify the specifications before choosing.
| Product | Best For | Listed Width |
|---|---|---|
| Babelio CatPrivilege III | Wide openings and adjustable cat access | 29–48 inches |
| Babelio CatPrivilege II | Extra height and adjustable small-pet door | 29–40 inches |
| Babelio CatPrivilege I | Buyers seeking an auto-close gate | 29–43 inches |
| 51-Inch Extra Tall Cat Gate | Extra-tall indoor separation | 30–49.27 inches |
| Carlson Extra Wide Dog Gate | Specific narrower openings and a walk-through door | 29–36.5 inches, with a gap |
Babelio CatPrivilege III Extra Wide Gate

This steel pet gate adjusts from 29 to 48 inches wide and stands 30 inches tall. Its cat door measures 7 by 5.5 inches and can be shifted between two positions. The product listing describes a double-lock design and an all-steel construction.
Best for: Homes with a wider doorway and different-sized pets. The adjustable cat opening is intended to let smaller pets pass while limiting access for larger ones. Choose this if a broad fit range matters more than extra gate height.
Consider: Its 30-inch height may not suit buyers looking for a taller barrier. Measure the opening and consider the size of the pet expected to use the cat door.
Babelio CatPrivilege II 36-Inch Gate

This gate is 36 inches tall and fits openings from 29 to 40 inches using two included extensions. Its 7.5-by-12-inch pet door has six height positions and a locking mechanism. The main gate swings in both directions, closes automatically, and includes a hold-open feature.
Best for: Buyers who want a taller gate and more control over the small-pet opening. It is a strong option for households that need hands-free closing or a way to keep the gate open temporarily.
Consider: Its maximum listed width is 40 inches, narrower than the CatPrivilege III. Confirm both the opening width and the pet-door dimensions suit your household.
Babelio CatPrivilege I Auto-Close Gate

The provided product name identifies this as an auto-close Babelio gate with a cat door, adjustable for openings from 29 to 43 inches. Detailed information about its height, cat-door dimensions, materials, and locking features was not included in the supplied product data.
Best for: Buyers whose opening falls within the stated width range and who specifically want an auto-close model. It offers a middle ground between the wider CatPrivilege III and the 29-to-40-inch CatPrivilege II.
Consider: The available details do not establish the gate height or cat-door size. Check the full listing for those measurements before deciding whether it will work for your pets.
51-Inch Extra Tall Cat Gate

This pressure-mounted gate is listed as 51 inches tall and adjustable for openings from 30 to 49.27 inches. Its name describes it as auto-close and intended for cats and small dogs in areas such as hallways, stairs, and kitchens.
Best for: Buyers seeking an extra-tall barrier for cat or small-dog separation. Its listed width range is broad, and its pressure-mounted design may appeal to shoppers who want that installation style.
Consider: The product name explicitly says it is not a baby gate. The supplied details also do not specify the cat-door dimensions or access mechanism, so confirm those before purchase.
Carlson Extra Wide Dog Gate With Small Pet Door

This 30-inch-tall metal gate fits openings from 29 to 36.5 inches, but its width range has a notable gap: it does not fit openings from 32 to 34 inches. It includes a small pet door with a locking feature and a 16.5-inch walk-through opening with a one-touch safety latch.
Best for: Buyers who want a walk-through gate and have an opening that falls within one of the listed fit ranges: 29–32 inches or 34–36.5 inches. Its small-pet door can allow a cat through while containing a larger dog.
Consider: Measure carefully because the 32-to-34-inch gap means this gate will not fit every opening between its minimum and maximum widths.
Buying Guide: How to Choose a Gate With a Cat Door
What width should you measure?
Measure the opening at the points where the gate will sit, then compare that measurement with the product’s stated range. Do not assume every width between a minimum and maximum is supported: the Carlson model specifically excludes openings from 32 to 34 inches. Also check whether extensions are included when the fit depends on them.
How tall should a pet gate be?
Compare gate height with the size and jumping or climbing habits of the pets you need to separate. The listed choices range from 30-inch gates to a 36-inch option and a 51-inch model. Height alone does not establish that a gate will contain every pet, so consider your pet’s behavior and the manufacturer’s intended use.
Will the cat door fit your cat?
Look for the cat-door dimensions and adjustment method, not just the phrase “small pet door.” The CatPrivilege III lists a 7-by-5.5-inch opening, while the CatPrivilege II lists a 7.5-by-12-inch door with six height positions. Compare those measurements with your cat and consider whether you need to lock the opening.
Do you need auto-close or a walk-through door?
An auto-close feature can reduce the chance of leaving the main gate open after passing through. The CatPrivilege II and the CatPrivilege I product name identify auto-close designs. For frequent movement between rooms, the Carlson lists a 16.5-inch walk-through opening and one-touch latch. Verify how each gate opens and closes in its full product details.
Is a pressure-mounted gate right for your location?
One listed model identifies itself as pressure-mounted, but the supplied details do not describe installation requirements for the other gates. Check the mounting instructions and intended placement, especially if you plan to use a gate near stairs. The 51-inch model is explicitly described as not being a baby gate.
