That's ok, I have edited my original postApologies
Regarding witches, yes, there are pros and cons to neutering before/after first season, some slightly outweigh the other, but generally so long as spayed before 2nd season (breed dependant) minimises most risks.
Evidence and research change, so always best to get most up to date evidence and a forward thinking practice, who change policies based on that, not just one who has a blanket policy that's been the same forever.
Sorry, back on topic now!
