The turtle has had free roam of my place for the last year and a half but I've had him for 3 years. Its previous owner used to keep it free roaming around as well and I've known this particular boxie for about 12 years now.
I did a quick comparison of box turle nail pictures that i've found with my turtle and the nails are not long nor curling besides what seems to be the norm.
His skin did look dry when I first brought him home but I've been using the vitashell. Every other day he gets a 15 minute soak and on the days he doesnt get soaked he gets sprayed with water. I know these werent things his previous owner did. His skin has gotten better since I first brought him home. I'll continue to watch for dry skin....
I did turtle proof the deck because I live on the 2nd floor. Its build out of wood and he gets a chance to go out in the afternoons. He has access to water and a 3.5 x 6 turtle pen with wood bedding, etc. Whenever possible, i do bring him to a friends house and put him the backyard but I'll admit I dont feel comfortable doing that and only do it if we are outside and he's under supervision. I'm always concern that he'll hide and I wont find him.
Please let me know if you have any other tips! I appreciate your time.
