HK Round Deep Pit Cat Scratching Board: A 45cm and 50cm Corrugated Paper Refill

This large round scratching board serves as a dedicated replacement refill for integrated cat furniture. Designed with a HK round deep pit pattern, it features substantial grooves across a corrugated paper surface, creating an effective zone for claw maintenance and natural scratching behaviour. Offered in two diameters, 45cm and 50cm, this cute style board provides a high-wear surface that can be fitted into various cat trees, condos, or wall-mounted systems, helping to redirect scratching away from household items.
Features and Construction

This product is built as a functional component, focusing on delivering a practical scratching surface for cats.
Material and Build
The board is constructed from corrugated paper, a layered paperboard known for providing the satisfying texture and resistance that appeals to a cat's instinct to scratch. This material is often used in scratching products due to its ability to withstand repeated clawing while being safe for pets. The 'HK round deep pit' style refers to the pattern of deep grooves etched into the surface, which cats can hook their claws into during scratching sessions.
Size and Practical Fit
Available in two specific diameters, 45cm and 50cm, this round board is sized to replace the primary scratching panels on many cat furniture units. Its large surface area provides ample room for multiple scratching angles and positions. The round shape is a common format for refill boards designed to fit into circular frames or platforms on integrated cat towers and activity centres.
Uses and Placement

As a replacement part, this scratching board has a clear, singular function within a multi-component pet setup.
Event or Professional Use
In multi-cat households, catteries, or pet-friendly accommodations, integrated furniture sees significant wear. This refill board allows for the replacement of the most heavily used scratching component without needing to replace the entire furniture unit. The deep pit design is intended to extend the usable life of the surface by providing more material to be worn down through scratching.
Everyday Home Use
For the individual cat owner, this board provides a straightforward way to maintain a cat tree or scratching post. When the original scratching surface becomes worn out or shredded, this refill can be installed to restore the furniture's functionality. Positioning it as the primary scratching target on a favoured piece of furniture can help consistently redirect scratching away from sofas, carpets, and walls.
Benefits and Buying Value

The value of this product lies in its role as a replaceable part within a larger system.
Reuse and Low Maintenance
The core benefit is the extension of your existing cat furniture's lifespan. Instead of discarding an entire cat tree when the scratching surface is depleted, you can install this refill board. The corrugated paper construction is designed to be worn down through use, and when it eventually needs replacement, the process can be repeated, making the supporting furniture frame a longer-term investment.
Why Choose This Product
Choose this scratching board refill if you need a specific 45cm or 50cm round replacement surface with a deep pit design. It is suitable for owners whose cats have a strong preference for corrugated paper textures and for furniture that accommodates this style of refill. Ensuring you have the correct size and pattern (HK round deep pit) is essential for compatibility with your existing integrated cat furniture setup.
