Cat Mate Elite Wall Liner (308) - Works with The 305, 355, 358 and 360 Doors for Easy Installation (Pack of 1)

Getting the correct invert really makes a difference.

these will lock into place with each other, but not with the inside the house side of the actual cat door. I was told I would need an additional glass door conversion piece. There is a work around. You can use a flat head screw driver to snap off the inner lip of the female side. Doing so means that you can then press this onto the inside the house side of the cat door.

Pensé era necesaria y la compré no la ocupe, es sólo si quieres expandir un túnel, la puerta pet ya trae un marco para ponerla entre algo delgado, está solo es si abres una pared o algo así.

Great fit for installation of my new cat door

The door installed perfectly and easily in my wall. I needed and purchased two wall liners, which worked well. The Locking mechanism works well with the collar tag; haven't had any issues yet, BUT my cat has still not gotten used to the SOUND the system makes when it is unlocking. The cat refuses to go through it at all and has ended up using various places within our house as a new impromptu litter box. When I would coax (read: kindly shove) the cat through the door, it would seemingly not take issue with the sound, and would go through relatively willingly; however when we would go to work for the day I guess she decided it wasn't worth the risk that there might be some hidden guillotine built into the door, and would instead use our carpet, tile, clean laundry basket, etc as a litter box. We never had this issue with the previous (non-locking) cat door that this one replaced. Now we have effectively left this door in the 'unlocked' mode for the last month - which defeats the purpose of us buying a relatively expensive electronic locking cat door.(by the way, we DID do all the recommended 'training' recommended by the manual - just when we put it back in the locking mode, the sound freaks the cat out :( ).

Does not fit the microchip activated cat door at all.

Good

Just as described. Worked well.
