Thanks your answers.
The enclosure of my tort is a transparent one (but not glass of course). As for its diet my tort has refused to eat anything but lettuce since I got it which is now more than 3.5 years. I told forum members and was told: "Try other food." I did but it just would not eat. So I kept feeding it lettuce. I soak it in warm water daily. I take it out for a "walk" in the sun when the weather permits.
As for change, well, I changed the carpet of the sitting room in Oct. 2014. My tort seemed astonished at the beginning but later on things went fine: it seemed to have got used to it.
Room temperature is almost the same day and night as I put on the central heating, making room temperature 24-25 degrees celcius. Isn't that ok?
As for the light it's on all night long. Is it too much?
Notice that my tort's been asleep since two hours now. Is it making up some sleep?
Your help would very much be appreciated. Thanks a lot in advance.
I really hope you understand, if you do not change the diet for the tort you will have a sick tortoise, period. I understand your desire to see the tortoise eat so you offer lettuce....however, that tortoise relies on you to do what you are suppose to do to assure its best health, which includes a diverse diet...does the tortoise graze on grass outside when you "walk" the tort?
The carpet change, was there any glue/adhesive used in the installation of the carpet? Do you let the tortoise run about on the floor of your home? What have you done in the prior years during winter time for the tortoise?
