I have a cockatiel named Bijou who is 8 years old. I brought her home from the pet shop at 8 weeks old having never had a bird before, only to find out she wasn't weaned!! She spent the first couple days crying (anyone who has ever handfed a bird will know how they sound when they cry out for food!) because she was starving! I didn't know what was wrong but I knew something definitely was so I called a bird store and the lady knew as soon as she heard her in the background what was wrong. She had to go back to the petstore for a few days for antibiotics and to be weaned, only to come back to me STILL crying out and not knowing how to eat! So I had to chew up broccoli for her to eat, and within two days she was eating her pellets. So she is very much my baby! She's really posessive and bites any cat, dog, or human than comes near me when she's out, and tells them off if she's in her cage and they have the nerve to do it. LOL She does not have her wings clipped, the only time she ever flies is when I first let her out of the cage, when she thinks I'm not paying enough attention to her, or on the rare ocassion that she wants to go back in her cage. I used to have her wings clipped when she was younger, but stopped because I really couldn't find a good reason for it.
As for the cats and Bijou, when Ruin my Siamese kitten came home we had to put Bijou in a cage with smaller bar spacing because Ruin would NOT leave her alone. She's still interested in her but there is no way she can get at her, and Bijou isn't the least bit flustered by it. I've had cats the entire time I've had Bijou and we've never even had a close call. As long as you're careful I'm sure your bird will be fine.
