Wow thats is terrible. I have no experience with pigs, but i know it must be very traumatic for you. Sorry man.
Discussion
in my first experience with a mother cat having kittens i learned that kittens die without the warmth of their mother, as their bodies do not have mechanisms to generate any heat (and cats in general have weak heaters inside them, they are nearly cold blooded)
and yes, usually cat mothers eat the cold dead babies that didn't make it, similar to the pig
and btw, 1/3 of kittens usually die, and they are eaten by the mother, most people don't even know this
Losses are unfortunate but expected, this is admittedly disturbingly macabre. Hopefully we’ll make the right changes and not see any more of this. Thank you. 🫂
