I have a 17 year old named Bingo. Unsure of sex, but we just call him a he. He is the most mischievous, intelligent pet ever--a regular home entertainment center. He makes upwards of 300 sounds, words and phrases. My favorites are "I'm naked" and "Got any food". He used to torture my former dog---I got them around the same time, and Bingo got all jealous, so he would tell Brodie he was a "bad dog" and try to bite him. He's mellowed with age and doesn't mind the new dog. Or the cats. In fact, he's quite tolerant of them and lets one hang out on top of his cage, so long as she doesn't try to play with his toys too much. He used to regurgitate for another cat I had---It was an inter-species love affair .

He also has what I call conversations with me. I suppose because he's learned what's appropriate as a response within conversations, he'll interject with "uh-huh" or "oh really". I doubt he understands what he's saying, but it's hilarious. He'll ring like a phone, say "hello", make some one-word responses, and then "ok, bye" and make the hang-up noise.

He'll eat pretty much anything you give him, so long as it's not sweet. He hates fruit, but loves anything salty, especially junk food like crisps and chips.

Oh, yeah, and like some other people mentioned, he burps. He tends to do that when he's happy--the Bingo Burp of Approval lol
