Mountain Cavies Association

Mountain Cavies Association, guinea pigs, Tooele, Utah, is a dedicated small breeder in Tooele County and the Great Salt Lake region near Salt Lake City. Founded by Emma Penrod over a decade ago, the association has maintained membership with national rodent clubs and follows health testing protocols recommended by leading breeders. Its cavy pairs are housed in ventilated enclosures with daily socialization sessions to support friendly, well-adjusted animals. It shares resources with new owners on guinea pig nutrition and habitat maintenance.

The association’s philosophy centers on natural diets and enriched habitats that reflect elements of native forage. Family visits are welcomed by appointment, offering insight into the rescue and rehoming efforts alongside breeding. A recent testimonial noted the calm temperament of a young boar, reflecting the care invested in every guinea pig through consistent handling and clean quarters. Emma Penrod emphasizes regular veterinary checkups to screen for common conditions like dental overgrowth and mites.
