The Alberta Animal Rescue Crew Society (AARCS) has brought in a massive intake of 50 rescued guinea pigs, and eight of the animals have tested positive for a highly contagious fungal infection. This is by far the largest intake of small animals in the organization’s history. AARCS is looking for donations to support the high costs of care for all of the guinea pigs.

The guinea pigs came to AARCS from a breeder after a few male guinea pigs escaped into a female-only enclosure, resulting in a large number of pregnant pigs. AARCS was unaware that several of the guinea pigs were infected with ringworm when they agreed to take the animals in. Each guinea pig had a comprehensive veterinary exam upon arrival, which is when AARCS found and tested the concerning lesions. Sadly, two of the guinea pigs had to be euthanized due to unrelated health issues.

“Taking in this many guinea pigs is already a massive undertaking, but adding in ringworm really complicates things,” said Amy Corpe, AARCS Director of Animal Health. “Because ringworm is highly contagious, we’ve had to test every single guinea pig at a cost of about $100 per test. Each pig needs two consecutive negative tests two weeks apart before they can be cleared. We also have to quarantine and treat each positive case, which in some cases can take months.”

AARCS is urgently seeking donations to help cover the costs of ringworm testing and medical care, expected to reach over $10,000.

“The easier and less expensive option would be to euthanize these guinea pigs, but we believe there is no life too small. Each and every one of these animals deserves a chance, and we’re doing everything in our power to give it to them,” said Corpe.

The organization is also reminding the public to be cautious of where they are finding their next furry family member.

“All of these guinea pigs came from a breeder that was supplying pet stores,” said Corpe. “When you choose to adopt from a responsible and transparent rescue instead of purchasing a pet, you’re getting an animal that has been cleared for adoption by a veterinarian and is ready to come home with you.”
