Right. As if AS does anything, AL.Lucas,
Perhaps you are as uncaring as the killer.
For those wishing to remove a stray kitty from one's property, simply call Animal Services and ask to borrow a trap. If none is available, call the Santa Cruz SPCA. Both agencies are more than willing to aid the public in trapping stray kitties, getting them off the streets, and relieving their suffering. Killing them, which may result in extreme suffering before death, is not the answer.
For those wishing to discourage stray cats from visiting one's garden, turn a hose on them. Doesn't hurt, and they learn very quickly. It's called behavior modification, with extreme prejudice.
