Why is my tortoise shell only growing on one side,? She is heavier on that side now so walks with a limp. Sadly I didn't know about fruit and she loves bananas, apples, and grapes but I will stop now. No-one has mentioned hibernation. Ours goes in a box of straw in the loft when she starts to close down in Autumn, and comes down in the Spring. She wandered into our garden 45 years ago and we couldn't find the owner. She now has a small address label stuck on her shell. Angela Joy.Hello and welcome.
D3 production happens fairly quickly in warmed tortoise skin. They don't need much UV to get the job done. Incidental walking around with access to sunshine for a couple hours, once or twice a week will get the job done. Indoors, I only run UV bulbs for 2-3 hours mi day. Which reminds me, there is almost no UV in morning or evening sun. UV levels spike mid day outside. Use this knowledge to time your outdoor sunning sessions. You can also use a calcium supplement with added D3 to ensure your tortoise is getting all that it needs.
As Tammy mentioned, pyramiding is caused by growth in conditions that are too dry. Pyramiding has nothing to do with UVB. The internet is full of all sorts of wrong info. Pets shops and vets aren't much better, and all of the above get their info from the same wrong sources.
Here is the correct care info for your species:
The Best Way To Raise Any Temperate Species Of Tortoise
I chose the title of this care sheet very carefully. Are there other ways to raise babies and care for adults? Yes. Yes there are, but those ways are not as good. What follows is the BEST way, according to 30 years of research and experimentation with hundreds of babies of many species. What is...tortoiseforum.org
And I agree about no fruit.
Questions are welcome!
