I answered it. You wanted to know why cat owners 'feel' that way. I told you. You are the one who is emotionally charged. You don't like a cat crossing your precious yard. But birds pooping, etc is ok. You have no right to capture someones cat and misplace it. Let it be....like I let my neighbors dog be when it feels like running behind my yard. Don't be so petty and cruel.
Faulty logic, failure to see a clear point, refusal to answer questions, failure to read concise posts clearly, inability to understand property rights, etc.
Good luck with your cat.
