I grew vegetables in my backyard last summer. But the neighbors here really like to keep their cats outside and they shit and piss in my yard. Including in my vegetable garden.

We also had these 2 birds make a nest above our backdoor. Then they had babies and after 2 days, the nest was empty and blood was everywhere.

If anybody has ideas, please tell me because i don't know what to do anymore.

There is so... many... cats... and people in my neighborhood are very shitty people. So asking them kindly to keep their shitty cats inside is a no no.

I have tried putting spikes on my fence but they don't give a shit. They still climb over it.
