What do Urban Animals Suffer From?

Here are some examples:

• Think about stray cats. We know most of them die at a very young age. They get hit by cars, starve to death, die from disease, and more. True for most wild animals, true for most urban animals as well. Helping them include spaying and neutering, creating homes for them, supplying regular food, vaccinations, and more.
• But it's not just cats. Other animals also suffer from similar things. Most urban pigeons are born into short, fragile lives: in some dense city populations, first year mortality has been estimated at over 80%. Egg swapping is an intervention that replaces real eggs with dummy eggs, which reduces the number of chicks born to die very young.
• Where I live in Israel, some hedgehogs suffer from a severe form of scabies. One likely reason is that cat food left on the street attracts hedgehogs too, bringing them into repeated contact around the same feeding spots. A simple fix is to place the cats’ food higher, where cats can reach it but hedgehogs cannot. Anyone who has seen a hedgehog with advanced scabies knows how awful it can be. Their bodies can be covered in thick crusts, sometimes so badly that you can barely see their eyes. They are helpless, it is hard to watch.
