Hi Samsam. I do not know if it is normal. However, we just brought our Star home 9 days ago and I had not seen any feces until yesterday. He finally went while I was soaking him. I've soaked him every other day since we brought him home. There was quite a bit so I don't know if being in a new environment threw off his system? He eats well, so I did not worry about it too much. Hopefully owners with more experience than me will weigh in too.
New torts can take weeks to settle in and behave normally.
However constipation is iften linked ti dehydration, especially in torts bought at pet stores.
Give your tort a soak every day for the time being. Some torts hate soaking to start, but they do get used to it and in any case it's tough, but it's for their own good.
My tips are:
1. Soak first thing before your tort has warmed up properly to reduce escape attempts.
2. Use a high sided bowl or box so your tort can't see out
3. Use enough warm (not hot) water to just come over your tort's plastron (undershell). Get the temperature right and your not-warmed-up tort is more likely to lounge and absorb the heat.
4. Soak for a good 20 minutes. Don't worry if you don't see him drink; torts can absorb water through the skin. The length of soak is important.
5. Your tort may wee and/or poop in the water - it's more likely to concern you than him. You can change the water if it's truly disgusting. Don't worry if your tort eats his poop; it's said to improve gut flora!
6. Feed straight after the soak. Joe is always hungriest straight after his.
By making the soak part of a morning routine, you wil also help your tort get used to his new home and he'll know what to expect
