MLive.com reports Karin Caston's cats have accepted the bird, named Peeps, since she found it about two weeks ago in her yard in Allegan County's Otsego Township, 35 miles south of Grand Rapids.
The bird lives in a cage, but spends time nestled in the fur of two of Caston's cats or perched on their backs. A third cat lets the bird walk around it. She tells The Associated Press in an email that she first locked up the cats when she started caring for the bird.
The robin also likes to hang out on Karin Caston's finger. She says the bird is expected to be released at an area park.
