Devastating: What a tortoise viral disease really looks like if it enters a group or collection.
A Testudo graeca overwhelmed by multiple secondary bacterial infections of the mouth, skin and eyes after contracting a highly contagious strain of Chelonian Herpes-virus. Andy Highfield Following on from our recent articles on the critical importance of having effective disinfection and quarantine protocols, we felt it equally important that keepers fully understand what happens if these should fail. Here are two real-life reports that detail exactly how traumatic this can b

Tortoise Epidemic: Quarantine and Barrier Nursing Techniques
By S. B. Fairbrass Recently imported Kinixys belliana (Bells Hingeback tortoises) suffering from a variety of health problems and potentially carrying unknown pathogens. All rescue centres need very high standards of disinfection, hygiene and robust quarantine protocols if epidemic spread is to be avoided. This is a reprint of an original article that appeared in the Tortoise Trust Newsletter, 1991, Issue 4. It was written by someone with a professional background in infectio

Centrochelys Sulcata Burrows, Substrates and Natural Habitats: Myth Busters Special Edition (Part One)
Centrochelys sulcata, The African Spurred tortoise, exits a burrow. Andy. C. Highfield From a species very rarely seen only 50 or 60 years ago, to a species that is now kept and bred in captivity in astounding numbers. In some ways this might be viewed as a success, but in other respects it has created huge welfare problems. The African Spurred tortoises grow to be very large tortoises indeed, just behind the Seychelles giant tortoises and the Galapagos giant tortoises. Typic

Introduced Fruiting Species in Tortoise Habitats
Humans have affected original, natural habitats in many ways. We call these anthropogenic changes. One these is by introducing agricultural species (from entirely different continents in some cases) into wild tortoise habitats. Wild tortoise species that would never, naturally, encounter such items. In addition, we change the very nature of these agricultural plant species by selectively enhancing them for increased size and sugar content. What are the impacts and implication

Why trusting ChatGPT can be bad for your tortoise: We put it to the test
Perfectly healthy wild growth. in a Testudo graeca graeca. Most captive tortoises are not so fortunate, however, and deformed, damaged examples vastly outnumber healthy ones. Poor quality advice and misleading information is a major contributor to this problem. We are increasingly seeing recommendations that people should rely upon ChatGPT and other, similar AI sources when they have questions about how to care for captive animals, or to learn about conditions certain species

How To Make Your Own Tortoise Or Turtle Egg Incubator
An Egyptian tortoise (Testudo kleinmanni) hatches in one of the incubators described here While you can buy commercial models, the "low cost" designs tend not to be very precise or reliable, while the "professional" designs are incredibly expensive. The good news is that you can make an incubator that will outperform all but the most expensive professional models at very reasonable cost and which is, in addition, very easy to build. by Andy C.

Nesting Sites and Egg F.A.Q. Updated
A female Testudo hermanni carefully positions her eggs Failure to provide adequate nesting sites in captivity can have serious consequences for heath, including an increased danger of egg-retention leading to possible fatal peritonitis. The lack of acceptable nesting sites can also lead to increased stress, and negatively impact upon captive breeding success. Tortoise nesting behaviour can be broken down into several distinct phases: Nest site selection Preparation of the nes

High Temperatures and Tortoises
There is a lot of concern (and misinformation) about how tortoises handle potentially dangerous high temperatures in the wild. No-one comes to hose them down or soak them! It can be weeks and even months between rains. So how do they really do it? By the careful and clever use of behaviours designed not only to gain heat when required (basking) but also by other behaviours that are highly effective at losing heat when necessary. This can involve shallow scrapes, as used by Me

"He Won't Eat Anything Else".... How to Handle Tortoises with Dietary Addictions
Perfect growth and development in a wild Testudo graeca graeca in her natural habitat. 100% wild plant diet and seasonal feeding and activity patterns. Andy C. Highfield Certain tortoise species in the wild typically consume a range of over 150 different plants during the course of a year ; the precise dietary makeup varies massively on a seasonal basis, as the plants come in and out of season. We have a very good video on this! The seasonal changes in vegetation within Test

Questions, Answers, Total Confusion and Sorting Fact from Fiction

There are exotic vets... and exotic vets. A cautionary tale.
This box turtle is in hiding... with good reason! In an ideal world all exotic vets would be fully informed about every possible species that comes through the door. They would not only have a thorough grasp of diagnosis, surgery and pharmacology, but also be able to give reliable advice on identification, feeding, housing requirements and behaviours. That is a pretty tall order, however, and we do not live in an ideal world. Exotic vets are expected to know virtually everyth

Tunisian Tortoise Care Updated
Tunisian tortoises showing typical shell, head and leg colour and patterns Tunisian tortoises belong to the spur-thighed ( Testudo graeca ) group of tortoises, but in 1990 they were described as a new species, nabeulensis , on the basis of their unique appearance and certain other morphological characteristics. In most older texts, they are still referred to as ' Testudo graeca ', however they are now widely recognised as at least a separate subspecies, ' Testudo graeca nabeu

Indoor Accommodation for Tortoises: A Practical Guide
A typical glass-style 'tortoise beginner kit' as often recommended by pet stores. This is, in reality, far too small, fails to offer a suitable thermal environment and also includes unsuitable substrates, inadequate lighting and heating, a poor quality unreliable thermometer and damaging pellet foods. Sadly, however, thousands of new keepers are mislead into purchasing combinations such as this. Tortoises raised in such units have incredibly high rates of metabolic bone disea

Should I soak my tortoise in carrot juice ? Myth-Busters: Episode 11 (and why AI can be bad for your tortoise's health)
Giant tortoises soak in a natural pond - but should it be carrot juice? Carrot juice soaks are often suggested on pet-keeper groups. It is frankly bizarre that such a question even arises, but it does, regularly. We'll get the easy part out of the way right up front: No. Absolutely not.
