If the cat returns on a regular basis, then it probably has no six year old little girl waiting at home for it. No caring cat owner would allow such a thing. If it continues to be a nuisance to you, you have no obligation to its owner, assuming it even has one. It has damaged your property, injured your pets while on your property, and presumably cost you some money on both fronts. I would kill it without hesitation, then chop its head off and put it on a stake in my front yard as a warning to all my neighbors. But that's just me...
