In the study1, which was funded by Universities Federation for Animal Welfare (UFAW), an online questionnaire was completed by 744 snake owners worldwide but predominantly from the UK (68.8%).
The questionnaire investigated housing and husbandry practices and snake health and welfare as measured by clinical signs and behavioural indicators.
Associations between clinical signs, behavioural indicators and housing and husbandry aspects were tested for the three most common snake families: Pythonoids, Boids and Colubrids.
The study found 54.7% of snakes were kept in enclosures shorter in length or height than their body, preventing them from stretching out fully.
10.2% of snakes in the UK were kept in enclosures that do not comply with current recommended guidelines (minimum enclosure length <0.66 of snake length).
Whilst most snake owners (93.1%) reported measuring the temperature in their snakes’ enclosures, 24% of these checked less than the recommended once daily.
When looking at the most commonly owned snake species (royal pythons, corn snakes and common boa constrictors), 47.2% were kept in sub-optimal temperatures for their species.
Furthermore, 48.1% of owners reported not measuring the humidity in their snakes’ enclosure.
Owners reported that many snakes experienced at least one of the listed clinical signs, with the most common issues being skin shedding (28.2%), parasites (11.2%), rostral cuts and scrapes (7.4%) and respiratory problems (5.6%).
Snakes that were kept in enclosures <1 snake length had significantly more clinical signs compared to those snakes kept in enclosures >1 snake length.
Similarly, most snakes were reported to experience at least one of the listed negative behaviours, most commonly interacting with transparent boundaries (52.8%), wincing or withdrawal of head when gently touched (52.4%), putting the head under the substrate (52.1%), unusually high level of activity (51.1%) and attempting to escape (45.9%).
All these negative behaviours have previously been described as associated with captive stress.
Snakes that were reported as having more clinical signs tended to show more reported negative behaviours.
Dr Nicola Rooney, Senior Lecturer in Wildlife and Conservation at Bristol Veterinary School and corresponding author for the paper, said: “Our study has highlighted various concerns for snake welfare.
"The first of these relates to enclosure size, with snakes commonly being kept in vivaria preventing straight-line postures and movement.
"Snakes that were unable to stretch out fully had more clinical signs than those that were able to stretch out fully.
“Whilst we did not find a significant association between temperature or humidity and measures of health and welfare in this study, it is a concern that many snakes were housed in conditions considered sub-optimal for their species.
"We know that appropriate temperature and humidity is vital for maintaining the health of snakes and it would therefore be prudent to investigate these associations further, using methods other than owner reporting.”
Dr Huw Golledge, Animal Welfare Editor-in-Chief, said: “Until now, there has been little empirical data on the housing and husbandry practices of privately kept snakes, and how these impact on their welfare.
"As the first study of this size, this research provides valuable baseline data against which future surveys or welfare interventions can be compared.
“As this survey relies on owner-reported information, it is very likely that many of the frequencies of clinical and behavioural signs are underestimated.
"This demonstrates the need for evidence-based recommendations, and the importance of such recommendations being made accessible to owners to improve snake welfare.”

The one-day event, called VetQuest, will allow prospective students to spend the day being mentored by a current student whilst getting involved in interactive sessions, such as large animal skills, clinical skills and veterinary public health.
Participants will learn about the opportunities available to those interested in pursuing a veterinary career, have a tour of the school and attend talks on vet admissions and work experience.
Dr Louisa Slingsby, Teaching Fellow and Faculty Admissions and Recruitment Officer at the Bristol Vet School, said: "VetQuest allows those who are interested in a career in the veterinary professions to come along for a day to find out more about the roles of veterinary surgeons and veterinary nurses.
"They will also have the opportunity to learn what to think about when choosing and applying for courses and how to give themselves the best possible chance to make an informed decision about if vet medicine is the career for them."
There will also be an optional session for parents and carers to help them navigate the challenges of applying to study to be a vet or vet nurse. The morning starts with a tour and then a talk and a Q&A session and finishes around lunchtime.
The cost of the one-day event is £50 and there are a limited number of subsidised places at £10. Lunch is included in the registration fee. To book visit https://www.bristol.ac.uk/vetscience/events/2018/vetquest-2018.html.
The event is primarily aimed at years 11 and 12, although anyone is welcome to attend.

The new course is called Veterinary Science: Accelerated Graduate Entry (BVSc), and will welcome its first students in September 2019.
The school says the course responds to calls for innovation in veterinary education while upholding current best practice in adult education to support independent, self-directed, and collaborative learning.
Designed for graduate learners, the programme will see students guided through case-based, tutor-facilitated teaching and learning.
The programme is based on a collaborative approach, where students can work together to gain practical experience from BVS clinics and clinical research.
Students will be taught in new purpose-built teaching facilities at the school in Langford, North Somerset.
The Langford Campus also encompasses equine and small animal hospitals, a dairy farm, diagnostic laboratories, and farm animal, small animal and equine practices.
Professor Richard Hammond, Head of Bristol Veterinary School said: "As someone who was a graduate entry veterinary student myself, I feel passionately about providing opportunities to those who make the choice to train as a vet later in their educational journey.
"This new programme, delivered in purpose built, state-of-the-art facilities will focus on a more student-centred, case-based approach in small groups and with lots of tutor contact and support. We look forward to welcoming our first cohort of students to Bristol in September 2019".
