Benjamin Graham –
Installed the Ani Mate #221 door on our 14-inch cat and it fits perfectly. The locking mechanism is solid and keeps the door secure. Works well with our thin wall panel and the cat uses it daily without any issues.
Sophie Piper –
Great fit for our large cat. The cut-out size matches our wall perfectly. The lock is strong and the door stays closed when not in use. Easy to install with no tools needed.
Madeleine Cornish –
We replaced our old flap with this one and it’s much more reliable. The 4-way lock prevents accidental opening and the self-lining works on our thin screen panel. Our cat is happy and the door is secure.
