Taking my Star tortoise to the vet today. Having a fecal exam. It has not gained weight in 3 months. It is 30 grams. I received it 0n 5/30/11 at 17 grams. on 7/22/11 it went to 33 grams. It stayed within 29-32 in the next 5-6 months. It is now 29 grams. I have another which is 204 grams that I received on 11/10/10 The poop that I have now is about 20 hours old. Unless I get another before I leave, will the vet get any info from this? What else can the vet tell me by just looking at him? He is active,looks good,eats well, and goes under the uvb lamp where it will stay for about an hour.
