Choosing a healthy reptile at the start saves heartache and vet bills later. This head-to-tail checklist covers eyes, nose, mouth, skin, body condition, behaviour and the enclosure it came from - plus the red flags that should make you walk away.
A healthy reptile is bright-eyed, alert and holds itself well, with clear eyes, clean nostrils, a neat mouth, smooth skin, a firm rounded body and a clean vent. It grips firmly and reacts to you. Check the animal head to tail, watch how it moves, and inspect the enclosure and other animals it came from. If several signs are off - or the shop conditions are poor - it is safer to walk away than to rescue a sick animal on impulse.
Choosing a healthy reptile at the start saves heartache and vet bills later.
Watch the animal in its enclosure first. A healthy reptile is usually alert and reacts to movement, with good posture - lizards holding themselves up rather than lying flat and limp, snakes with steady muscle tone. Look at the whole setup: is it clean, correctly heated and lit, not overcrowded? Sick animals often share an enclosure, so check the neighbours too. Ask how long the animal has been there and whether it is feeding.
Start at the head. Eyes should be clear, bright and full - not sunken, cloudy (unless in shed), swollen or crusted. Nostrils should be clean and dry, with no bubbles, mucus or crusting, which can signal respiratory infection. The mouth should close neatly; look for any drooling, cheesy material, or redness that could indicate mouth rot. Breathing should be quiet - open-mouth breathing, wheezing or clicking is a serious warning sign.
Start at the head: clear eyes, clean dry nostrils and a neatly closed mouth are core health signs.
Run your eyes over the body. Skin should be smooth and even, without retained shed, scabs, lumps, discolouration or visible mites (tiny moving dots, often around the eyes and vent). The body should feel firm and rounded, not bony; a well-muscled tail base is a good sign of nutrition, while a thin, wrinkled tail or prominent hips suggest a underweight or dehydrated animal. Check the vent is clean, with no stuck faeces or swelling.
A firm tail base, clean vent and strong grip suggest good condition; a thin tail or dirty vent is a warning.
When gently handled, a healthy reptile has good strength and grip, moves smoothly and evenly on all limbs, and rights itself easily if tilted. Weakness, tremors, wobbling, dragging a limb, or a star-gazing/head-tilt posture are all reasons for concern. A calm, alert animal that simply dislikes being held is very different from one that is floppy and unresponsive.
Should I buy a slightly unhealthy reptile to rescue it?
It is tempting, but impulse-rescuing a sick reptile often means high vet bills, an uncertain outcome, and rewarding poor seller practices. If welfare concerns are serious, raise them with the seller or relevant authority rather than buying on the spot.
Is cloudy eyes always a bad sign?
Not always - eyes go bluish-cloudy before a shed, which is normal. But cloudiness with discharge, sunken eyes or other symptoms is different and warrants caution.
How can I tell if a reptile is the right weight?
Look for a firm, rounded body and tail base without visible hip or rib bones, appropriate to the species and age. When in doubt, a reptile vet can assess body condition properly.
Do I need a vet visit even for a healthy-looking new reptile?
A new-pet check with a reptile-experienced vet, including a faecal test for parasites, is a wise investment - many apparently healthy reptiles carry internal parasites.
