Study reveals most common guinea pig disorders
Overgrown nails were the most commonly seen condition.
Researchers examined clinical records of over 3,500 guinea pigs.

Overgrown nails, ringworm, and eye ulcers are the most common conditions seen in pet guinea pigs in the UK, a new study has found.

Researchers from the VetCompass research programme at the Royal Veterinary College (RVC) analysed anonymised clinical records from a random sample of 3,785 guinea pigs which were under primary veterinary care in the UK in 2019.

The records showed that overgrown nails were by far the most recorded disorder, seen in 26.55 per cent of guinea pigs. The second most common issue, ringworm, affected 6.02 per cent of the animals in the study, and 4.99 per cent had an eye ulcer. Other common health issues included anorexia and abscesses

Males were found to be more likely to have bite injuries, anorexia and dental problems such as overgrown incisors, whereas females were more likely to have eye disorders, such as coreal ulcerations, and abdominal masses

The research also revealed that females lived longer than males, with female guinea pigs having a life expectancy of 4.56 years compared to the males’ 3.74 years.

As several of the most common disorders are linked to sedentary lifestyles, the authors believe that the findings can help veterinary professionals advise guinea pig owners about providing the right conditions and care to keep their pets healthy.

Dan O’Neill, lead author of the study, said: “This study highlights that many of the most common health issues of pet guinea pigs are related to how we keep them as pets in captivity.

“With this new awareness, owners can better understand the world from the guinea pigs' perspective and provide exercise, bedding and nail care to ensure these wonderful creatures enjoy healthier lives.”

The study has been published in the journal PLOS One.

Practices urged to audit neutering data

News Story 1
 RCVS Knowledge has called on vet practices to audit their post-operative neutering outcomes.

It follows the release of the 2024 NASAN benchmarking report, which collates data from neutering procedures performed on dogs, cats and rabbits.

The benchmarking report enables practices in the UK and Ireland to compare their post-operative outcomes to the national average. This includes the rate of patients lost to follow-up, which in 2024 increased to 23 per cent.

Anyone from the practice can submit the data using a free template. The deadline for next report is February 2026.

Visit the RCVS Knowledge website to complete an audit.

RCVS pays tribute to well-loved equine vet

The RCVS and the Riding Establishments Subcommittee has paid tribute to well-loved veterinary surgeon and riding establishment inspector, Rebecca Hamilton-Fletcher MRCVS.

Linda Belton MRCVS, RCVS President, said: "I, along with my colleagues on the RESC, RCVS Council, RCVS Standards Committee, as well as RCVS staff, was very saddened to hear of the sudden death of Rebecca, or Becca as we knew her, last week.

"She was a true advocate for equine welfare and in her many years on the RESC worked to continually improve the quality and consistency of riding establishment inspections, all in the interests of enhanced horse welfare and rider safety."
