We have hedgehogs, and have had for several years. We have had a battle of increasing complexity to prevent neighbouring cats from eating the kitten food we put down for the hogs. Currently we are using a large fruit box from the grocer to cover the food trays. Weighed down with bricks to stop the cats moving it.
There is one stupid/determined cat which spends hours each night trying to break into the covered area. Generally, I think, with no success. However I would like to discourage it without having to rush downstairs and bang on the back door. Which only works for a short while.
Previously we have discouraged cats using a super soaker, so a water spray is effective.
Looking on the Internet, you can get electronic hose timers which can be controlled over wifi. This is attractively geeky. Sit up in bed, press the button on your phone, short spray of water towards the cat.
There are a variety of options:
Does anyone have experience of these products? I would like one which can send a very short burst - a second would do - of mains water pressure through a nozzle on the end of a garden hose. Controlled by an Android phone app.
Cheers
