Usage tips
Use with 'lassen'
Since the action is usually carried out by a veterinarian, 'kastrieren' (to castrate / neuter) is very often used in a construction with 'lassen' (to have something done). The subject of the sentence is therefore the person who gives the order.
EXAMPLE
Wir haben unseren Kater letzte Woche kastrieren lassen.
We had our tomcat neutered last week.

kastrieren vs entschärfen
to defuse
'entschärfen' and 'kastrieren' can both mean, in a figurative sense, that something has a weaker effect. But the tone is very different. 'entschärfen' sounds neutral or positive: you make a situation calmer, wording less harsh, or a rule less strict. 'kastrieren' is much stronger and is usually meant negatively. It says that something is weakened so much that important content or its actual force is lost. The words can be confused when talking about changes to texts, rules, or proposals. If the change sensibly calms or softens something, 'entschärfen' fits. If you want to criticize that something has been cut back too much or made ineffective, 'kastrieren' fits in the figurative sense.
kastrieren
Durch die vielen Streichungen wurde der ursprüngliche Vorschlag fast kastriert.
