We have lots of feral cats around my neighborhood. I myself am a pet owner and love my animals. I got into air gunning because of ground squirrel issues when I moved into my new house(21 years ago now) and have since done in thousands of them over the years. Lately, their have been old, sick, wild tomcats that come to my backyard. I trap them and have them neutered (or euthanized if they are sick and beyond treatment) when possible. However, many of these cats are wiley as hell about traps and are very difficult to catch. I hate to see animals suffer. If I cannot catch a cat and have it peacefully euthanized, would my airgun be sufficient to put a full grown feral tom cat down? I have a 22 cal pcp rated at 30 foot pounds of energy. It would break my heart to wound an animal. So, my question is two fold- if I were to use my air gun to put a wild cat down, would 30fte be enough gun to do the job efficiently and painlessly? I know when it comes to hunting that shot placement is way more important than power- so what is the best part of the animal to aim at in order to kindly dispatch a suffering cat? Have any of you ever had to do this? Please, no pics of cats you have killed. It just hits home too deeply for me.
