Newby here, I have gone from 0-5 tortoises in the past year: 2 Greek Spur thighed (now approx. 10 months old) purchased for my kids/ family. Living on table with cedar chips. 2 mature Spur thighed (aged 2 & 3yrs - doubt ages are accurate) - rescued. Living in viv- cedar chips. 1 Hermann's (approx. 10 months) - adopted. Living on table with tortoise substrate. Any advice or guidance welcome.
