Oh and another really good tip if you have a cat that keeps getting in your yard and shitting everywhere....
Take a glass bottle and smash it up, then, get some spackling and spread it across the top of your garden fence.
As soon as you have spread the spackling on the top of the fence, liberally sprinkle the broken glass shards over the spackling and gently push them down with a spackling knife.
I guarantee it'll stop the cats from coming in to your garden
PLUS it also stop neighbourhood kids from jumping your fence to get to the river
Regards,
