Steve continues to make small progress. Over the weekend, I put a new toy in his cage, as you can see here. It has clear plastic cups for foraging. He worked hard, but kept dropping the nuts to the bottom of his cage, so I ended up moving it down so he could get at them from the cage bottom. I didn't want him to get too discouraged!He mastered that, so this toy will slowly be migrating back up, incrementally increasing the level of foraging difficulty.
This morning, he spoke to me in context for the first time. As I was leaving for work I said, "I'll be back!" and he responded with "I'll be back!"
On Sunday, I was out at a play, and Thomas was upstairs doing practice test questions (he has to take his board exams later this month). He said that Steve chattered pretty much nonstop for a couple of hours.
Now we've just got to get him wanting to come out of his cage, but we'll get there!
