The Sacramento SPCA on Sunday was housing nearly 300 rabbits seized from a home in nearby Folsom last week.
Police and animal control officers who responded to a house on Pine Grove Way in Folsom on Friday afternoon found 54 rabbits and transported them to the SPCA. Later that evening, they collected 232 more rabbits from the home and took them to the shelter.
Officers seized the animals because city code in Folsom allows only two rabbits per household, and the living conditions for the rabbits were unsanitary, Folsom police said.
"There was definitely a smell," next-door neighbor Jake Allen-Barfield told televison station KCRA of Sacramento.
The SPCA is now seeking supplies and cash donations to help care for the rabbits. One of their tweets used the hashtag #bunnyoverload2018.
