Unsuitable as a cat bell

We have taken a stray since the summer, who wants just purely out how it fits in. As we were the patio door did not want to constantly leave open in the winter, we have gekauf this mat. A friend has a similar mat, but whose is clearly better. The mat is it quite thick and then a doormat ... neee hangover did not go on it, but constantly get past it. Then finally, when he was going out on it, but bell did not go on. Did the cat a few so enticed him to go to the mat, but he is probably too easy. Did it then with a full carton of milk tasted ... Again the bell rang after a few tests on.

Conclusion: The cat must be so trained that they just sit on these points (or is). Mat went back again.
