I wouldn’t have shot the cat with an arrow, nor would I have bragged about it online.
Do you put a collar on your cat? Do you spay, neuter, and vaccinate your pets? If you are not doing these things, you are an irresponsible pet owner.
Both of my cats are indoor..neutered, collared....never a hint of trouble to any other human being. I keep them sheltered, and have done so for their entire lives.
