To euthanize an old sick cat?

that would probably be best, but dont overdose the cat, her last minutes could be panicky, i suggest doing that, then waiting 4 her 2 fall asleep n using a gun, so she ill die in her sleep........... I love aniimals, but sometimes u havt do what u havta do...... but get some kind of shot or something,, and dont OD her, cuz her final minutes could result in her struggling 4 breath, instead of peaceful........ hope this helps
