The little bird did not save, so frequent cleaning of mini solar collector. The cat of my neighbor completely crazy ... (no effect on him ....) But personally it wasnt the goal, my goal> away martens, ferrets, etc .... my barn and my BIG BIG aviary. Since my animals are spared ... (ie, it works either, predators are afraid of dubious aesthetic;)
I had already experienced this type of repellents ... Offered as repellents "chicken predators" I'm not certain that these repellents are suitable for rats and cats;)
The finish is basic, simple, not giving the sensation of being eternal;)
