I have 2 keets as well. I got two for the same reason Tweety Pie said, I don't have a ton of time and I worry about their safety outside their cage with my cats, so I wanted them to have a mate/friend.

Gertie is WAY, WAY, WAY more vocal than Maurice, but if you cover the cage (at night), they are quiet.

Mine love to go outside (in their cage). They are really, really fun to have.

I also switch their toys each weekend so they stay occupied. They have a lot of fun toys out now, so they enjoy that.
