I assume you are this critical of the ecological damage caused in order to make the computer you are whining about a fucking cat on, right?
Discussion
I don't believe I'm whining, I love both cats and birds. I'm merely pointing out a way to keep them both. And besides that I'm pointing out a logistical fallacy and the misinterpretation of the term natural selection.
Its a cat. Cats are part of nature. Like all living things. If this single cat throws something out of balance, there are bigger problems thana cat
Let me ask you this. Have you ever witnessed the end result of a cat killing everything in the area and bad things happening ecologically as a result? Because I have seen this exact claim of your many times, yet, I let one of my cats out every night, plus there are multiple strays at any given time. Yet there are still birds, squirrels, snakes, rabbits, chipmunks, etc. This is a narrative that appears to have zero basis. Like all environmental narratives.
Another logical fallacy, this time the anecdotal one. I could give you multiple academic sources (a simple google search would suffice as well), but I don't think anything could convince you really. The fact that your cat hasn't faunacided the whole neighbourhood isn't particularly conving evidence that it's all made up. I wish both you, your cat and all the birds in your neighbourhood well.
