The abstract alone already provides fodder against the pack-leader hypothesis: animals in a cougar domain are more likely to get T.gondii, and it might have altered the cougar's behavior instead, which would be more in line with the proposed mechanism behind rat and hyena behavior modification. And I think the only one that's got more decisive evidence is the one where the rodent becomes less afraid of a cat's smell.

Not saying it can't be the case. But the linked article is bad (ok, I should have seen that coming), and there's a lot left to disprove before the conclusion can be drawn. Yet the reactions already want to test politicians for infection, as if there were no leaders before cats were commonplace, and as if it isn't known to be bad for pregnancy.
