Blackbird in my garden

In summer the male common blackbird is visiting my garden from time to time and looking for rain worms and other insects that hide in the grass. Since my garden has a lot of natural elements like parts that I don't mow and some parts with sand. Birds like it very much since they can find insects there and can also use the sand as a repellent for parasites. The common blackbirds like to search for worms in the grass and I already observed it several times that they found a big worm and flew away. Unfortunately the neighbor has a cat so I am still a bit in two minds about preparing a feeder and some water for the birds. I have to find a nice model that is catproof and save for them.
