I have two Three-toed box turtles I was able to get as hatchlings. Their now 5 yrs old and have a length of 3.5 in. scl and a width of 3.0 in. scl. They have mostly been inside pets but this summer they were outside during daylight hours. I think they have put on about a half inch in size this summer. Does this seem small to anyone? Thanks for all the replies, Jack
