Overview
The Cat Mate 304 is a magnetic-latch cat flap sized for small to medium cats, built to mount into a screen, UPVC or wood door in white plastic with a two-way locking tunnel.
Two-way locking means the flap can be set to swing freely in both directions or locked shut entirely, rather than the four-way in-only, out-only, locked and free control that microchip models offer. It comes with installation hardware for fitting into an existing door panel.
- Model 304W, white plastic frame
- Sized for small to medium cats
- Magnetic closure with two-way lock
- Mounts into screen, UPVC or wood doors
Who it's for
For owners who need a basic entry point for a cat sharing a household with no other pets to keep separated. Not a fit for anyone who needs to control which individual cat can pass through.
Pros and cons
- Magnetic closure resists drafts when unlocked
- Two-way lock seals the tunnel for overnight use
- Installation hardware included
- 3 year manufacturer guarantee
- No microchip or selective locking for multi-cat households wanting to restrict access
- White plastic only, no color options
Performance notes
The magnetic closure holds the flap shut against wind and drafts when it's set to free-swing, and the two-way lock lets the whole tunnel be sealed for overnight use. Cat Mate backs it with a 3 year manufacturer guarantee.
