Works halt ...

Our cat had always an open basement window, which was covered with concrete up to their size. Worked logically fine. But since now it is quite cold in the basement,
I needed a solution - especially since we already had two strange cats in the house.
We ordered the Pet Porte, they employed directly into the brickwork, fixed with polyurethane foam and fixed installation edge new. Keeps.
Now to use: the cat can be the beginning of clacking of the bar, the springs open easily, and the flap is put off staying away.
But with the right bait, some time later, the fear of the enemy in our garden, we were able to bring it now to the flap
accept. The part now works properly for half a year.

Small drawbacks are available for the installation options: as we have the flap inserted into Meuer work, we had to extend the tunnel. And each tunnel parts
are not under tension when they are plugged into each other, but are quite loose. We then tried it with foam, but the spreads. This has become the
relatively thin plastic warped and the door has jammed. Here I had to play with a file and rework.
Also, I must give my speakers right about the bolt itself. Real stable he is not. I put out that the tunnel (as has been said, with me
three elements extended) inside is so long and straight that a cat does not have the grip to apply the force to break by force the flap.
Conclusion: if there is no other way, certainly worth a try. The mechanism itself works fine, only the processing still leaves to be desired.
