Great pictures of Cobi and your fish!!!! I also live alone and so it is only me that Ana Grey usually interacts with. When I talk to her, I talk to her like a person. "want some apple", "nite, nite", "stop that" as examples and she picks up on the meanings. And she does know what words mean. When I sing, she always says now, "STOP THAT" do you think she is trying to tell me something!!!!!
