Sorry to keep asking questions about this tortoise! I foster a sully on the weekends because his owner does not feed him and heʻs left alone in a 3X5 open-top enclosure outside, among other things. We donʻt have the types of predators you do, but we do have mongoose and feral cats. He is almost 3 years old, and while I understand that they have wildly different growth rates, Iʻm afraid that this guy - who isnʻt even the size of a football will get eaten or attacked. On the weekends when I have him, he is able to graze in my yard for about 6 hours a day, and we also take a 45-minute walk down the street (on the grassy dirt median ) every day that I have him. Would it be too stressful to keep moving him on the weekends? I put him in a small animal carrier with towels and on colder days, a sock of warm rice and a dryer heated towel to cover the crate. Itʻs about a 25-minute drive.
