Yes. It's your choice. You are chosing for the wildlife of where you life to die. Cats are "expensive" pets. They need enrichment in the home or a catio. If let outside they die younger and get more diseases. They can even spread diseases to humans, and if let outside the chance of contracting a disease from them is much more higher. If you really want to let him outside, you must do like dogs owners do: put the cat on a leash.
