This is Georgie and Heidi when I first got them. They were about the same size. Georgie (on left in pic below) is a Leopard tortoise; Heidi (right) is a Sulcata tortoise.
The picture below was taken April 23, 2015.
This next pic was taken July 21, 2015. Heidi (on the left) started growing like a weed!

And then Today, November 14, 2015.

On Nov 12th, Heidi was 831 grams.

They are both growing fast, but Heidi is putting on 200 grams every 2 weeks.
