I remember watching my dad castrate hogs, I don’t remember seeing them bleed like a “stuck hog” - no pun intended.
Cut the sack, split the membrane, squeeze the nut out and cut cord and make sure other nut doesn't get sucked in when you are on the first, then Betadine over sack...and if it is an animal that has annoyed you use metho.
For a cat cut the corner off a hessian bag and drag his tail back through it exposing his nuts, sit on the bastard to keep him still.
