our neighbors were cat owners like that. they took care of the strays and were constantly fighting to get them all fixed. when we got a solitary kitten from them, they had a momma kitten and two of her daughter kittens who all gave birth at the same time, who the vet would not snip because he doesn’t do abortions. on the third attempt of “look, she just had kittens what do you mean she’s pregnant again” he just snipped them because 17 kittens is too many kittens.
