I'm worried that my old guy is on his way out. Is it normal for older toads, close to passing to stop eating? Also, today he has started acting very weird - he keeps trying to climb out of the terrarium. He's walking all over the place and doing a lot of moving around. Before today, he and his buddy have always hidden inside their rock decoration. I'm just worried about him. I haven't changed anything about their food. I know he hasn't eaten in about 4 weeks except for 1 cricket. Help. I'm bummed and don't want him to die.
