Very effective repellents against cats!

The hundreds of cats who have our beds as a toilet new purpose of the housing estate, are now looking to gradually another alternative. The sprinkler distributes cats alone already by the sudden noise when it triggers. The free shower then does the rest.
On the first night of the sprinkler is felt 10-20 tackled times. On the second night only 3-5 times. We have heard him by the open window, or in the morning all was wet switch. Meanwhile dare even again several smaller birds on our lawn which was otherwise really an exception. Now the sprinkler is not more than 1-2 times at night. Sometimes he stays even and dry.

Since our property is large and winding with long hedges and many loopholes I have the sprinklers now quite a few times changed. Every time it has again produced the same positive effect. I very much hope that this painless conditioning long does because in the winter we have the sprinkler disconnect because risk of frost.

Contrary to other reviews I find is the part of the turf very stable. Since moving almost nothing. In flower bed with loose soil it is still a little shaky. But is nevertheless the Sprenklerdruck stand.

Resistance: For this we can say that I immediately ordered an added role Teflon tape. This is definitely everything (!) Tight. Clear: There is a risk, of course, still in the lead (garden hose). A newly purchased original Gardenastecker has proved itself here. Was thinking possibly a buffer tank for example from an old house waterworks (25 liters) to clamp between. That would reduce the risk of the water costs drive up if nevertheless times the hose flakes off at night.

The sprinkler triggers sometimes wrong from sunlight. Especially when just was a cloud above the house and the sun begins to shine again, he starts again. Thereafter, however, is again quiet.

Conclusion:
Although a bit more expensive but who wants to drive animals from the property really should be equal access to water and skip the cheap ultrasonic acoustic or smelly alternatives! Strong buy recommendation for cat haters!

Addendum 2 months later:
Neighbor's cat now always comes down the road went, shortly before the walkway to our property, she stops, looks to the house and then goes on to the opposite side, where the dog behind the fence is. Seems they probably preferable to the Sprinkler System ... As soon as she has the plot happens it returns the road. Unique success!
