    Hyenas more closely related to cats, vs dogs.

    Anyone else find this amazing?
    The females have to give birth through a pseudopenis which usually causes the 1stborn to asphyxiate.
    Apparently the females have very high testosterone levels.

    Within Order Carnivora, hyenas fall within sub-order Feliformia, along with cats and civets, rather than Caniformia, along with dogs.

    I've heard about females' pseudopenis from other sources, and that it leads to difficult childbirth (though not specifically about asphyxiation).

    That explains it then. They are laughing AT us.

    The risk is perhaps overstated. There's a good review of spotted hyena litter sizes here. "Only" about a third of litters undergo reduction in numbers from the in utero to neonatal count, of which 80% are stillbirths and 20% resorptions - so maybe a quarter of litters have stillbirths, though there are no figures on birth order of stillbirths (because hyena parturition is very rarely observed). Stillbirths more common in primips, which would certainly fit with some problem with a tight birth canal.

    ETA: As far as I know, out of four hyena species it's only spotted hyena females that have a pseudopenis.

    I had thought they were related to the mongoose.

    Yes indeed. More closely related to mongooses and meerkats (Viverroidea) than to cats (Feloidea), but more closely related to cats than dogs.
