Twinmom0804 --- So happy to hear they're doing better!
What you described sounded a lot like getting-to-know-you-ness, but a bigger cage will definitely be appreciated, I'm sure!
Zebs are super pushy; even more so in a small space. But at least they're not being nasty. From what you described, it sounded like they were pushy, but not aggressive and nippy, which is always a good thing.
Harley2013 -- That's funny about your dog!
We've had tons of rats over the years. I just love them. We had those giant rat-sized hamster balls and I don't know if you know about rats, but they're super curious. So they would try to walk up to the dogs and cats, who were simply horrified by this creature in a bubble! Ultimately, it turned into a situation where the rats would chase the cats and dogs. If the rats could talk, you could tell they would have been yelling "Hey you! Big furry creature! Get over here! I want to check you out!....Maybe nibble on your toe a bit. Come baaaack!..."
Fortunately, my dogs pretty much ignore the birds, with the exception of my Min Pin, but she's not a bother (thank goodness, as Min Pins are also ratters and they can be super determined!) She was rescued from a puppy mill and had likely never set foot outdoors before her rescue. She was absolutely amazed by all things outdoorsy and natural.
She literally spends hours sitting and watching the birds and when she's not watching my birds, she's sitting in the window watching them outdoors! It's super cute.
