We are a first time tortoise owner so any advise about feeding and cleaning will be very helpful. We have had our new tortoise since Friday and today it has decided to claw one corner of her tank. Also, we were told that it is a couple of months old and that it was ok to feed it parsley, carrots, blueberries and green peppers but my granddaughter takes it outside and it seems to like the grass in our yard better. Should we be feeding it the stuff we are? One more question, we were told it is a female but they weren't too sure, how do we tell?
