Apart from keeping rats under control and your cat well behaved, belled up and preferably inside at night, there is alot we can do to make our properties wildlife friendly. For example skinks need debris to hide under, so an overly sterile site is not skink friendly. Leave some branches or logs in a corner of the garden. You will be rewarded by having little skinks in your garden. These in turn help keep unwanted bugs under control. Having bird feeders in cat friendly places in also a great idea.
