I have two Adult Red Foot Tortoises (Male & Female) named Dora & Houdini. Dora's 11' & Houdini is 8.5' in SCL. They got a big outdoor enclosure 12x10 ft, heavily planted with lots of hide. They eat mostly fruits, a portion of greens and very rarely boiled chicken meat. Humidity is high most of the time. They also get plenty of sun heat from late spring up until early fall then they are moved inside with supplemental heating and misting. They've been with me for more than 2 years and I never had any issues with them since. Lately, Houdini (Male RF) has been constantly trying to escape. He's very stressed in wanting to climb from the 2 ft wall, and spends the entire day trying to escape. I am equally stressed in tying calm him down with soaks or treats but to no good. Any idea on why he's suddenly anxious to escape and what's the remedy to this?
