Hurray for you and for Oscar! Keep us posted. The only new perch that seemed to initially alarm my rehomed TAG, Timber, was the boing. I added other perches to his cage without him reacting much. He wouldn't necessary hop right on them, but they didn't seem to scare him. It took him some time to start liking the boing, but now it is his favorite thing to do the "sit and chew" on. That said, every bird is different. Timber's vet said to never use a sandpaper surface type perch because it can hurt their feet. Others with more experience will chime in. God bless!
