Cat Mate 221W Large Cat Flap – White 4-Way Locking

The Cat Mate 221W Large Cat Flap is a generously sized, manually locking pet door designed for larger cats and many small dogs. Finished in classic white with a transparent flap, it provides independent access for your pet while giving you complete control with its 4-way locking system.

Designed for everyday use, the Cat Mate 221W features a brush-sealed flap with magnetic closure to help reduce draughts and improve weather resistance. Its self-lining design makes it suitable for many timber, uPVC and panel doors up to 50mm (2") thick.

Large Cat Flap for Bigger Cats & Small Dogs

The generous 180mm × 180mm flap opening provides more room than a standard cat flap, making the Cat Mate 221W suitable for many larger cats and appropriately sized small dogs.

Typical pets may include:

• Maine Coons
• Ragdolls
• British Shorthairs
• Norwegian Forest Cats
• Bengals
• Yorkshire Terriers
• Dachshunds
• Pekingese
• Miniature Poodles
• Cavalier King Charles Spaniels

Please measure your individual pet before ordering. Breed examples are a guide only, as animals of the same breed can vary considerably in size.

4-Way Locking Cat Flap

The Cat Mate 221W gives you four access settings, allowing you to control when your cat or dog can enter and leave.

• In & Out – allows your pet to enter and leave freely
• In Only – allows your pet to come inside but prevents them going back out
• Out Only – allows your pet to leave but prevents re-entry
• Fully Locked – prevents access in either direction

This is particularly useful when you want to keep your pet indoors overnight or restrict access at particular times of the day.

Brush Seal & Magnetic Closure

The transparent flap incorporates an effective brush seal and magnetic closure. These help the flap return to its closed position after your pet passes through while reducing draughts and improving protection against the weather.

The magnetic action also helps prevent the flap moving unnecessarily in windy conditions, providing quieter everyday operation.

Self-Lining for Doors up to 50mm Thick

The Cat Mate 221W incorporates a self-lining frame for doors and panels up to 50mm (2") thick. This provides a neat finish through the installation opening without requiring separate tunnel sections for most standard door applications.

Suitable applications include:

• Timber doors
• uPVC door panels
• Suitable PVC panels
• Metal doors
• Garage doors
• Utility room doors
• Garden rooms and suitable outbuildings

Always check the construction and thickness of the installation area before cutting.

Wall Installation

The Cat Mate 221W can also be used for suitable wall installations. The optional Cat Mate CP400 Wall Liner can be used to create a neater tunnel through the wall and is available separately.
