Stuck Shed, and the Toes It Threatens
African fat-tailed geckos come from the dry edges of West African grassland but shelter in humid burrows and termite mounds, and that humidity is what new keepers most often get wrong. Kept too dry, a fat-tail sheds in stubborn patches instead of one clean skin, and the leftover rings around the toes are the danger: they tighten as they dry, cut off circulation, and can cost the gecko the toe tips entirely. A humid hide that is always available, and a check of every toe after each shed, prevent most of it. Shed skin lingering on the eyes is equally serious, since a gecko that cannot see properly cannot hunt.
Mouth Rot, Breathing Trouble and Soft Bones
Mouth rot shows as reddened, swollen gums, sometimes with a cheesy discharge, and a gecko that stops striking at food it normally takes eagerly. Respiratory infections follow cool or persistently damp setups: listen for clicking or wheezing, and watch for bubbles at the nostrils or breathing with the mouth held open. Metabolic bone disease is the quiet one — a jaw that feels soft or bends, limbs that bow, a gecko that drags its belly instead of walking tall. It builds over months when feeder insects are not dusted and gut-loaded properly, and the earlier it is caught, the more of it can be steadied.
Parasites and the Weight That Quietly Disappears
A large share of African fat-tailed geckos in the trade have travelled a long way from wild-caught or farmed origins, and internal parasites travel with them. The pattern to recognise is a gecko that eats, or tries to, yet loses condition: runny or unusually smelly droppings, a shrinking tail, ribs becoming visible. Because parasites are diagnosed from droppings rather than guesswork, a faecal test at an exotics vet is the sensible first move for any new fat-tail and for any established one that starts to fade. Treating blind, without knowing what is there, wastes time the gecko may not have.
The Tail as a Health Gauge
This species carries its savings account in its tail, which is why the tail is dropped only as a last-resort escape — and why a regrown one comes back shorter and plainer. Read the tail like a fuel gauge. Plump and smooth means reserves are good. A tail that thins week by week while the gecko still has access to food means something is consuming those reserves: parasites, infection, stress from a too-busy enclosure, or temperatures that keep digestion sluggish. Weighing the gecko monthly and noting the tail's shape beside the number turns a vague worry into evidence you can act on.
When a Fat-Tail Needs the Vet, Not More Time
Some signs should not be watched at home. Shed skin constricting a toe, a tail thinning quickly, gaping or bubbling breath, a jaw that feels rubbery, eyes sealed shut, or a gecko that has refused food for weeks while losing weight — each of these has a cause that home care cannot fix, and small nocturnal geckos decline faster than their size suggests. Bringing your notes helps more than you might expect: KinsLe's Pet Passport keeps your gecko's weights, shed dates, faecal results and visit summaries in one packet, so the vet starts from the animal's real history.
