Very interesting to watch their interaction with other animals (in my opinion). I have four cats. The cats ignore Timber for the most part. They will stick their paws up on his cage and peer at him through the bars once in awhile. He will let them know he doesn't appreciate it much the way Alfie does, by biting at the cage bars. Timber, on the other hand, is very interested in the cats' behavior and movements. He makes a very loud noise (can't really describe it but like something hitting the floor) when they are all in the room then laugh when they all startle and run. He also like to hang off the bottom of his cage when out and try to get a nibble of their tails when they pass under him. I have to say he doesn't bite hard though, because they just look startled rather than yowling. Like you, I don't take chances with him being too close to each other because you never know. He certainly has the meow perfected! When I'm in another room, I can't tell if it is Timber or one of the cats. I just thought the "alert" was interesting and wondered if anyone else's bird did that!
