https://www.vetsurgeon.org/f/clinical-questions/8148/diet-for-collared-geckos I have a client with three collared geckos - the environment conditions are good, but they seem to have recurrent problems digesting a diet of mini meal worms and small hoppers, with a slow down in metabolism and gut blockage. I have got them going againen-USTelligent Community 10https://www.vetsurgeon.org/thread/37071?ContentTypeID=1Wed, 04 May 2011 11:19:36 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:5bdec141-48fa-4909-a66d-dfec09a7ada0eddapb<p>They sound like lizards (tail, head, pores on thigh), but I will get picture next&nbsp;time client is in.&nbsp; I am not sure my client would know what taxonomic means ... o dear.&nbsp; Yet they can be very adamant about what they &#39;know&#39;, ie what the pet shop owner told them - especially if she was told how rare they are.&nbsp; However, from what you say,&nbsp;I think a major problem is the drop in temperature at night, especially if they are teh lizards we suspect they are&nbsp;- when hospitalised we keep them much warmer overnight, and they have rallied. I will get client searching for silk worms - she is enthusiastic if somewhat misguided. Thanks for your help!</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/37068?ContentTypeID=1Wed, 04 May 2011 10:50:05 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:22594c07-1de2-43cd-b08c-7928deaecc84Marie Kubiak<p>Collared lizards have a long, slender tail (typically longer than body) with body length up to about 30cm, collared geckos have shorter, wider tails. Gecko head is flattened compared to collared lizard. Are any male as male charcteristics are clear? - V-shaped line of wide scales on tail base, caudal to the vent and pores along medial thigh in collared lizards, and V shaped line of pores cranial to the vent in geckos. Can you get photos next time one&#39;s in if still not sure?</p> <p>Ask the owner for the taxonomic name - there&#39;s lots of different species falling under &#39;Collared gecko&#39; so they should know which species they have if it truly is a gecko. I&#39;d be concerned about their knowledge and the non-specific conditions provided if they didn&#39;t know the species.</p> <p>Once species is confirmed then look first at husbandry - for normal GI function temperature and calcium balance are key factors. Temperature and heat source type and position must be correct for the species. UVB lighting and calcium supplementation necessary.</p> <p>Intermittent partially impacting food suggests incomplete digestion so I&#39;d be concerned about temperatures first. Temporarily changing to lower chitin foods until the underlying issues are identified and resolved will help. Waxworms are readily available and accepted well but aren&#39;t a staple diet, silkworms are better but harder to source. Newly moulted mealworms (they show pale colouration) can be offered but need high numbers of adults to give sufficient numbers of moulted ones daily.</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/37065?ContentTypeID=1Wed, 04 May 2011 10:30:31 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:bd3b0a0b-c289-4cd5-9b77-a5ff818a1279eddapb<p>The owner insists they are rare collared geckos, but from the morphology, I suspect you may be right and that they are collared lizards from what I can see on reasonably reliable sources on Google images.&nbsp; However, I have not found a picture to absolutely rule out that they are geckos.&nbsp; Any obvious pointers,&nbsp;to differentiate are much appreciated!</p><div style="clear:both;"></div>https://www.vetsurgeon.org/thread/37057?ContentTypeID=1Wed, 04 May 2011 10:00:42 GMT146601cc-3922-4be7-9974-7e1d4e45a66b:f869eed2-2ceb-4985-8340-5fd2e9030e9cMarie Kubiak<p>Are they definitely collared geckos? These are rare in the pet trade. More common are collared lizards, a small iguanid.</p><div style="clear:both;"></div>
