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.

Bluetongue reaches Wales for first time in 2025

The Animal and Plant Health Agency (APHA) has revealed that bluetongue has been confirmed in Wales for the first time in 2025.

In their latest statistics, APHA records a total of 109 cases of BTV-3 or BTV-8 in Great Britain in the 2025-2026 vector season.

The total number of BTV-3 cases in Great Britain this season is 107. This includes 103 cases within the England restricted zone and four cases in Wales.

There has also been two cases of BTV-8, which were both in Cornwall.

As a result of the cases in Wales, a Temporary Control Zone (TCZ) is enforced in Monmouthshire. Animals can move freely under general license within the England Restricted Zone, however animals with suspected bluetongue must stay on their holding.

All premises testing positive for blue tongue can be viewed on this map.
