Yeah pretty sure you're just projecting some fucking weird issue here. That story has nothing to do with the dog.>>15778
Cats definitely should stay indoors or in a fenced in garden (fencing which they can't get over, so like, high). Dogs on the other hand need to be walked (but don't leave them outside all the time either, it's kinda fucked up IMO). The problem of cats killing birds is due to negligent owners that leave them outside (which is also bad for their health).
