Cat Mate 221B Large Cat Flap – Brown 4-Way Locking Cat Door

The Cat Mate 221B Large Cat Flap is a generously sized, manually locking pet door designed for larger cats and many small dogs. Finished in classic brown, it is particularly well suited to timber, woodgrain and darker uPVC door panels.

The Cat Mate 221B combines a spacious transparent flap with a 4-way locking system, brush seal and magnetic closure, giving your pet freedom while allowing you to control when they can enter or leave.

Large Cat Flap for Bigger Cats & Small Dogs

The larger opening makes the Cat Mate 221B a good choice for cats that find standard cat flaps too restrictive. It can also accommodate many smaller dogs, provided their measurements are suitable.

Typical pets may include:

• Maine Coons
• Ragdolls
• British Shorthairs
• Bengals
• Yorkshire Terriers
• Miniature Schnauzers
• Border Terriers
• Dachshunds

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

4-Way Locking Cat Flap

The Cat Mate 221B gives you four access settings:

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

This makes it easy to give your pet freedom during the day and keep them securely indoors overnight or whenever required.

Brush Seal & Magnetic Closure

The transparent flap incorporates a brush seal and magnetic closure designed to help the flap return to its closed position after your pet passes through.

This helps reduce draughts and weather penetration while also providing smooth, quiet everyday operation.

Brown Cat Flap for Timber & Woodgrain Doors

The brown frame complements many timber, mahogany, rosewood and brown woodgrain-style doors and panels, making it a discreet alternative to a standard white pet flap.

Suitable Installation Locations

The Cat Mate 221B can be fitted into many suitable door and panel applications, including:

• Wooden doors
• Timber door panels
• uPVC door panels
• Garage doors
• Utility room doors
• Garden rooms
• Suitable outbuildings

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