My sister’s Texan mother-in-law used to catch rattlers for a living - she kept them in some sort of cage out back and a guy would come every week and take them away. When I met her, she was on the back side of eighty and had had to give it up, but boy! she was still a pistol.
Lots of folks do that outside the city........ yer extended MIL sounds like a tough ole bird !
