Removing ovaries in humans is associated with a plethora of diseases (Wikipedia). Spaying dogs was shown to have negative effects in multiple studies (see here). However, for cats it is claimed that spaying hardly has any negative effects or even worse, that it's overall beneficial.
How is that possible? Isn't the biology of humans, dogs and cats similar enough that spaying should produce similar effects in these species? Is veterinary science really that stupid?
